Engineering the properties of electrical contacts relies on a detailed understanding of the physical mechanisms of charge injection, which govern charge transport across metal-semiconductor interfaces. For semiconductor nanowires, whose crystal structure, Fermi level pinning at surfaces and binding energies of impurities depart from bulk materials, this must be systematically re-evaluated to realise high-performance contacts using conventional metals or transparent conductive electrodes. To improve our fundamental understanding of the electrical contact to (semiconductor) nanowires, a PhD student will be involved in the study of nanowires with single and multiple probe scanning tunneling microscopy in ultrahigh vacuum at variable temperatures.
Detailed information of the nanowire surfaces will be relevant to understand the atomistic processes that may occur on the sidewalls during the formation of electrical contacts to the nanowires. Nanoscale characterization of band alignment and physical description of charge transport mechanisms through metal-semiconductor interfaces will be performed to optimize charge injection between NWs and metallic electrodes. In collaboration with companies, tools will be developed to study (i) the dynamics of charge carriers in the vicinity of metal/semiconductor interfaces and (ii) the local strain/doping induced in the semiconductor by the formation of a metallic contact.
This research fellowship programme (PhD) will be carried out within the context of the INDEED network, a Marie Skłodowska-Curie Actions– Innovative Training Network (ITN) – project funded by the European Commission, under their H2020 program. Through the project activities, the Fellows/PhD students will have the opportunity to come in contact and collaborate with some of the best European research groups.
