PhD examiner for Vasilis Georgiadis

Patrick was the internal examiner for Vasilis Georgiadis, a member of Dr Darren Graham‘s research group in Manchester. Vasilis defended his thesis entitled “Terahertz-driven manipulation of electron bunches using dielectric-lined waveguides“.

New Publication - Distinguishing cap and core contributions to the photoconductive terahertz response of single GaAs based core–shell–cap nanowire

Our recent work on single-nanowire terahertz detectors has been published in a special issue of the Lithuanian Journal of Physics, celebrating the 70th birthday of Prof. Arunas Krotkus. In this work, Dr Kun Peng used single-nanowire terahertz detectors with different capping to understand the relative contribution of the core and

New Publication - The influence of surfaces on the transient terahertz conductivity and electron mobility of GaAs nanowires

In research led by Hannah Joyce (University of Cambridge), and colleagues at the University of Oxford and the Australian National University we have reported an in-depth terahertz study of the influence of surfaces on carrier recombination in nanowires. By performing power-dependant and diameter-dependant measurements, Hannah determined the surface recombination velocity

New Publication - Single n-i-n InP Nanowires for Highly Sensitive Terahertz Detection

Kun Peng has written a paper accepted in IOP Nanotechnology (http://iopscience.iop.org/article/10.1088/1361-6528/aa5d80). The work, building on previous progress in single nanowire terahertz detectors, uses a combination of an axial doping profile and novel optical characterisation to improve the contact quality for these devices.

Rank Prize Funds - a view from Conor

Conor, a UoM 4th year undergraduate has spent the summer working in the lab (see here for details). He has been kind enough to describe working on a long summer project in the group: This summer, I spent ten weeks designing, building, and testing a terahertz time domain spectroscopy system

Goodbye and thanks to Conor!

Over the past 10 weeks, Conor Wilman (a UoM undergraduate) has been working with the group developing a low-cost and easy method of doing terahertz spectroscopy, known as terahertz quasi-time-domain-spectroscopy. His work, funded by the Rank Prize Funds Summer Studentship has been in trying to replicate this technique in the
