Renewable hydrogen production by solar photoelectrochemical water splitting: fabrication and characterization of semiconductor and catalytic materials [MQS1]

 Position open for a master student in the fields Electrical Engineering, Applied Physics or Chemical Engineering. Water splitting, also known as artificial photosynthesis, is a process that separates water into hydrogen and oxygen, by using sunlight as a source of photoelectrochemical energy. This process enables the production of clean, renewable hydrogen, which in turn can be used as fuel, or drive other chemical reactions. The most promising active materials for this process are semiconductors, such as III-V thin films (GaAs, InP, etc.) and metal oxides (hematite, bismuth vanadate and many others), but the current technological challenge rests in increasing their efficiency and their durability, by engineering their bandgap (doping and nanostructuring), and by increasing their resistance to corrosion (protective and catalytic coatings).

 The student will be involved in the fabrication, processing and characterization of the material, by nanofabrication techniques, optical spectroscopy, photoelectrochemical characterization.

The position will provide hands-on experience in a laboratory and in a cleanroom environment and knowledge of research methods and protocols. The work can also be extended into a master's thesis. Contact: Prof. Ilkka Tittonen

Plasmonic nanoparticles fabrication and optical characterization, for energy applications [MQS2]

Position open for a master student in the fields of Electrical Engineering, Applied Physics or Chemical Engineering.
The phenomenon of surface plasmon resonance arises from the interaction between light and electrons in a metal or in certain semiconductors: relevant applications are the enhancement of light-induced charge separation in a semiconductor, and plasmon-induced heat generation (thermoplasmonic heating). Both of these applications are significant for the realization of energy harvesting materials, such as the ones described in our other postings MQS(1) and MQS(9) and on photolectrochemical water splitting, and MQS(5) carbon based electrode for electrical energy generation from water evaporation. The work focuses on the design, fabrication and characterization of noble-metal plasmonic nanoparticles, with the goal of incorporating them in our energy-harvesting materials. The position includes hands-on work in laser laboratories and in a cleanroom environment, and/or modeling and simulations, and can be extended into a master's thesis.

Theoretical and/or experimental work on novel materials for carbon dioxide catalysis [MQS3]

Position open for a master student in the fields of Electrical Engineering, Applied Physics or Chemical Engineering.Managing the levels of carbon dioxide in the Earth's atmosphere is of utmost importance, and one way of achieving it is by catalytic reduction of CO2 into other compounds. CO2 is however a challenging molecule to reduce, requiring investigation in both the theoretical and the pratical aspect. The student will deal with simulating the interaction between CO2 and solid catalytic materials (metals and metal oxides) using a coupled-cluster model, and/or with the synthesis and the characterization of the catalytic materials. The position includes hands-on work in nanofabrication laboratories and in a cleanroom environment, and/or modeling and simulations, and can be extended into a master's thesis.

2D materials for printed thermoelectrics [MQS4]

Printing is a promising route for fabricating next generation electronics. Exfoliated two-dimensional nanomaterials such as graphene and some transition metal dichalcogenides have shown promise in thermoelectrics, which are materials capable of harvesting waste heat and converting it back into electricity. The position consists of experimental hands-on work on developing printable ink formulations containing 2D nanomaterials, as well as testing and optimizing their performance for inkjet printing. The job contents will be tailored to suit the academic level and skills of the selected applicant – the work can be extended into a thesis work.

Control electronics for a stand-alone energy harvester [MQS5]

Energy harvesting devices based on porous carbon black films are capable of generating voltages of up to 1.5 V by harnessing the potential difference generated by evaporation-induced water flow through the film. The technology shows promise for powering stand-alone sensors and similar devices in remote or hard-to-reach locations.

We are looking for an applicant with skills and interest in developing control electronics for the above-described devices. The system should include a supercapacitor or an alternative energy storage component along with a suitable MCU solution to control the charging and supplying of power to external devices.

The position provides experience on designing electronics for internet-of-things applications in addition to hands-on electronics development. The job contents will be tailored to suit the academic level and skills of the selected applicant – the work can be extended into a thesis work.

Experimental quantum illumination [MQS6]

It has been discovered in the last 10 years or so that quantum properties of electromagnetic waves can be used to enhance measurement sensitivity. For example, the quantum entanglement between pairs of photons makes it easier to detect photons that are reflected off some target. This setup is called quantum illumination. The applications of quantum illumination range from low-intensity optical measurements via quantum microwave radar to quantum communication and cryptography.

The task for this summer project is to assist in the experimental realization of the quantum illumination setup. The aim is to study how the measurement sensitivity of the system depends on various factors, such as background noise, distance of the object from the receiver, etc. Depending on the level of the student, this summer project can be extended to a thesis work.

Role of entanglement in quantum computational speedup [MQS7]

Currently several quantum algorithms are known (e.g., Shor’s factoring algorithm), which offer a significant speedup compared to the fastest known classical algorithm for the same computational task. The source of the quantum speedup is not yet well understood, although it is suspected that quantum entanglement between qubits plays an important role.

The task for the offered summer project is to track and visualize the time-evolution of quantum entanglement during the running of various quantum algorithms to explore the connection between entanglement and quantum speedup. As for example the current cryptography methods are threatened by quantum computing, and new quantum-safe methods are currently under development, understanding better the limits of the quantum computational speedup has profound implications for cyber-safety, among other applications. Depending on the level of the student, this summer project can be extended to a thesis work.

Genetic design of quantum algorithms for problems related to post-quantum cryptography [MQS8]

The current cryptography methods are threatened by quantum computing, and new quantum-safe methods, the so-called ‘post-quantum’ cryptography (PQC), are under intense development. The proposed PQC methods are based on certain mathematical problems that are believed to be too difficult even for quantum computers to solve. However, as the exact limits of quantum computing are currently not well understood, it is not totally clear if the proposed PQC methods are truly quantum-safe.

The task for the offered summer project is to take part in the automated development of quantum algorithms for problems related to PQC. Genetic optimization will be used to generate new quantum algorithms. We will then study the efficiency of the quantum algorithms thus discovered. This work may have important implications for the safety of the proposed PQC methods. Depending on the level of the student, this summer project can be extended to a thesis work.

Simulation of semiconductor-based materials for renewable hydrogen production by non-equilibrium Greens Function method [MQS9]

While photoelectrochemical cells have been successfully used to split water into hydrogen and oxygen since 1972, the physics behind the photoactivated electrochemical reactions are still not well understood. Non-equilibrium Greens Function (NEGF) formalism is a mathematical method that can be used to accurately calculate the charge carrier dynamics at nanoscale in a semiconductor excited by light. The task for this position is to further develop an existing quantum kinetic computer model of the semiconductor electrode of a photoelectrochemical cell and to use that model to design prototype electrodes. Knowledge of semiconductor physics, quantum mechanics and MATLAB/python are considered an advantage. Suitable for students who wish to continue to a master's thesis.

Manipulating light at the nanoscale [2D-Nano]

Manipulating light at the nanoscale is possible in specially designed structures of nanometer size. For example, some devices can confine light in a small volume, which can be used for the study of interesting physical phenomena, such as the hybridization of light combined with matter. This hybridization consists of a provision of matter properties to light, which is naturally massless. Providing light with matter properties opens up the opportunity to explore exotic ways of energy transfer, and possibly to realize science-fiction tools like the light sabers depicted in the Star Wars movies. The successful candidate will join an ongoing experimental research on this topic. In this research we combine light and matter in specially designed devices. This allows us to explore how light-matter hybridization modify properties of materials. The successful candidate will have access to the excellent research environment and handle the advanced optics techniques in the photonics group.
