Our group develops semiconductor nanomaterials for a wide variety of applications, including future optoelectronics, photonics and electronics.

The group is led by Dr Hannah Joyce. We are based in the Electrical Engineering building and make extensive use of experimental facilities throughout West Cambridge. We are a member of the Electronic Devices and Materials group in the Electrical Engineering division.

We have expertise in III–V nanowires, which combine the excellent electronic properties III–V materials, and the tiny dimensions of the nanowire geometry. These properties make III–V nanowires outstanding candidates for future electronic and optoelectronic devices, including light emitting diodes, lasers and solar cells. Our research endeavours to grow these nanowires controllably and reproducibly, to understand understand their fundamental optical and electronic properties, and to implement novel devices based on these nanomaterials.


Stephanie Adeyemo has joined us to undertake her PhD. Welcome to the group, Stephanie!
