Rank Prize 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
summer students Thanks (and bye) to Manish Thanks to Manish, who completed his 6 week summer project in the group. Over this time, he developed (and redeveloped) code to allow for repeatable location of single almost-identical nanowires. In the end, by building on an approach designed by astronomers his code was able to location unique features known
ANU New Paper - Broad Band Phase Sensitive Single InP Nanowire Photoconductive Terahertz Detectors Kun’s paper “Broad Band Phase Sensitive Single InP Nanowire Photoconductive Terahertz Detectors” has been accepted for publication in Nano Letters. In the work, Kun has fabricated a single nanowire terahertz detector using an InP nanowire, and compared different antenna structures with traditional “bulk” InP detectors. We have shown the
Nanowires Welcome to Manish and Conor! We welcome two University of Manchester physics undergraduate students to the group for a summer project. Manish Patel joins us to spend 6 weeks looking at how to identify the same nanowire twice on a substrate of 100,000 – not an easy challenge when they all look the same! Conor
