Arturo Alanis Arturo speaks at Nanowire week 2017 Arturo spoke at Nanowire week 2017 in Lund, Sweden today. In his first talk at an international conference, he presented his recent work on “Large-scale statistics for threshold optimization of optically pumped nanowire lasers” to a large audience of nanowire growth and characterisation experts from around the world.
Import 2022-12-08 21:42 Congratulations to Dr Peng! Kun Peng has been given approval for the award of her PhD for her thesis “III-V Compound Semiconductor Nanowire Terahertz Detectors“. Congratulations to Kun for all her hard work.
Nanowires Manchester Pint of Science Patrick spoke at the Manchester Pint of Science event at Terrace NQ. Linking the first photograph to nuclear bombs, the Matrix movie and helicopters that appear not to move, he described the use of picosecond “movie-making” to understand energy processes in photosynthesis and nanolasers.
Bryce Dorin New Publication - Direct laser write process for 3D conductive carbon circuits in polyimide Bryce Dorin has had a paper accepted for publication in the Journal of Materials Chemistry C, on Direct laser write process for 3D conductive carbon circuits in polyimide. Using a femtosecond direct-laser-writing technique, Bryce demonstrated 3D writing of conductive pathways in polyimide, a stable insulating material. Through optical and processing
Hannah Joyce 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
ANU 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.
MPhys Welcome to Pawita and Cosimo The group welcome two MPhys project students, Pawita and Cosimo, to the group. Over this semester, they will be working on developing a compressive-sensing approach to large area photocurrent mapping for novel photovoltaics.
Arturo Alanis The group goes to Oxford Arturo, Xiaoyan, Stefan and Patrick visited Oxford for the UK III-V Nanowire workshop hosted at Corpus Christi College. While Arturo presented a poster and Patrick a talk, the whole group got to meet the ever increasing number of researchers working on III-V Nanowires in the UK.

Arturo Alanis Arturo passes 1st year viva Congratulations to Arturo, who has passed his 1st year viva and now continues into the PhD program. His project will focus on the understanding of inhomogeneity in nanowire lasers, and their development towards device-implementable nanomaterial.
kun peng Kun Peng has submitted! Congratulations to Kun Peng, who submitted her PhD thesis today at the Australian National University. Her thesis, entitled “III-V Compound Semiconductor Nanowire Terahertz Detectors” has been completed under the supervision of Prof. Jagadish, Prof. Tan and Prof. Fu at the ANU and Patrick at the University of Manchester. Well done
kun peng MRS Fall - Invited Talk Patrick has given an invited talk at MRS Fall 2016 in Boston, on the topic of “Nanowire Photoconductive Detectors for Terahertz Time-Domain Spectroscopy”. The research is based on the work of group member Kun Peng, and specifically covered the characterisation and development of single nanowire terahertz photoconductive detectors.
Stefan Skalsky Welcome to Xiaoyan and Stefan! A warm welcome to Xiaoyan and Stefan who join the group today. Xiaoyan will be studying for an MPhil, looking at nanowire heterostructures for optoelectronics, co-supervised by Dr David Binks. Stefan is studying for a PhD co-supervised by Prof. Wendy Flavell, to understand energy dynamics in novel materials for photovoltaics.
Rank Prize 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
i-TCSPC New Grant - Royal Society Paul Instrument Fund The group has been awarded a grant by the Royal Society to develop a new optical instrument known as the i-TCSPC. The Paul Instrument Fund, established by the late RW Paul, is intended to help the design and construction of a new piece of apparatus. The new apparatus will leverage
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
