Position: Research Fellow in Room Temperature Single Electron Transistors, fabricated using STM
Institution: University College London
Department: London Centre for Nanotechnology
Location: London, United Kingdom
Duties: The Postholder will work towards the fabrication of single electron transistors (SETs) that operate at room temperature, using two approaches, (i) Fabricate ensembles of dopants from precursor molecules (e.g. As from AsH3) using chemical vapour deposition (CVD), then use scanning tunnelling microscopy/spectroscopy (STM/STS) to generate atomic-scale maps which can be exploited to fabricate SETs using an established method. (ii) Use STM hydrogen resist lithography to define SET structures where a single dopant is placed between two electrodes in UHV. Subsequently use ambient AFM local anodic oxidation (LAO) to induce tunnel barriers around the dopant, which will act as the SET island
Requirements: Essential: considerable experience of using UHV STM and STS at cryogenic temperatures; experience of using STM to perform lithography or to manipulate atoms in a controlled manner; experience of studying gas adsorption and reactions on surfaces in UHV, using STM; a track record in publishing high-quality research; Desirable: some experience of using local anodic oxidation with AFM to write oxide patterns in surfaces; experience of fabricating nanoscale semiconductor devices using cleanroom techniques
