Photodetector New Paper : Towards Substrate Engineering of Graphene-Silicon Schottky Diode Photodetectors A new paper describing the development and characterisation of high-speed Graphene-Silicon Schottky photodetectors has been published in RSC Nanoscale. The work, led by PhD student Hakan Selvi and Tim Echtermeyer includes high-speed device characterisation performed in the Parkinson lab. The new devices are broadband, high-speed, large-area and low-cost photodetectors which
Ken Crozier Manchester-Melbourne Linkage Scheme Patrick Parkinson (Manchester) and Ken Crozier (Melbourne) have been awarded linkage scheme funding to establish a collaboration. This funding, established by the two universities, will allow bilateral exchanges to exploit areas of expertise at the two institutions. This project will explore nanostructured silicon materials developed by the Crozier group using

IOP Nanotechnology IOP Nanotechnology Patrick has been invited to sit on the newly formed Advisory panel for the Institute of Physics journal, Nanotechnology.
Nanowires Seminar at the University of Jena Patrick gave the Solid-State Physics seminar at the University of Jena on Friday 16th June, on the topic of “Statistical Study of Disorder for Nanowire Optimization” at the invitation of Prof Carsten Ronning and Dr Robert Röder.
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.
Import 2022-12-08 21:42 One year in the lab... We are now one year into our new lab space, and it’s starting to look more used! The three experimental stations can be seen at the bottom right of the photo – transient microscopy, 3D material processing and automated microscopy (left to right).
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.
