Project Description

The field of semiconductor nanowires (NWs) has become one of the most active research areas in the nanoscience community in the last five years. Integration of semiconducting NWs with the well-established capabilities and low-production cost of silicon is crucial for the implementation of novel quantum emitters, such as single photon sources on Si.

Development of this area requires control of the nanowire structure, and the ability to map structural and electronic properties with atomic resolution. With the recent advances in hardware, such as aberration correction, electron microscopy is the technique of choice to disentangle the structural properties of the material and correlate them with the functional ones.

This project will involve the atomic scale characterisation of a range of semiconducting NWs, supplied by our internationally leading nanowire collaborators. The aim is determine the atomic scale structure and composition of the NWs, and to correlate these to changes in optical properties and electronic structure. Calculation of the critical dimensions for plastic relaxation of axial heterostructures in Nws is also anticipated. The candidate will be joining a group with an internationally-competitive electron microscopy facility with excellent specimen preparation and microscopy and many years of experience studying semiconductor materials. Strong collaboration with external partners at Universities (UCL, Sheffield and Lancaster universities) and semiconductor industries (Hitachi and Huawei) will be an essential part of the project."
