Tim Crothers - PhD viva in Oxford

Patrick acted as external examiner for Tim Crothers, a student with Prof. Laura Herz in Physics at Oxford University. Tim defended his thesis on Charge-carrier transport and recombination dynamics in metal halide perovskites.

Tutorial Session at Jaszowiec 2019

Patrick gave a tutorial session at the Jaszowiec 2019 meeting – the International School and Conference on the Physics of Semiconductors – held in Szczyrk in Poland. The session covered the use of ultrafast spectroscopy for developing nanotechnology for optoelectronics, and specifically semiconductor nanowires. A copy of the presentation is available for

UK Semiconductor Nanowire Meeting 2019

Patrick spoke and both Arturo and Stefan gave posters at the 2019 UK Semiconductor Nanowire Meeting, held at Corpus Christi College in Oxford. The event was chaired by Patrick and Michael Johnston (Oxford Physics), and it brought nearly 35 researchers from 10 universities together to discuss nanowire research in the

New Paper - Highly-Strained III-V-V Co-Axial Nanowire Quantum Wells with Strong Carrier Confinement

A new paper has been accepted for publication in ACS Nano. This work, led by Dr. Yunyan Zhang and Prof. Huiyun Liu at University College London, describes the growth and characterisation of quantum-well tube nanowires based on GaAs-GaAsP heterostructures. This work brings together partners from UCL, Sheffield, Warwick, Lund (Sweden)

New Paper - Two-Dimensional Diffusion of Excitons in a Perylene Diimide Monolayer Quenched by a Fullerene Heterojunction

James Kerfoot, supervisor Prof. Peter Beton and colleagues at the University of Nottingham have had a paper accepted in J. Phys Chem. C on exciton diffusion in monolayer organic materials in a collaboration with our Manchester group. In this new work, advanced AFM techniques are coupled to optical micro-spectroscopy to

New Arxiv Paper - Visible and infrared photocurrent enhancement in a graphene-silicon Schottky photodetector through surface-states and electric field

Nawapong Unsuree has submitted a new paper to the Arxiv reporting on work coming from a recent collaboration between the Echtermeyer group (Manchester) and the Parkinson group. The research was conducted in the National Graphene Institute and the Photon Science Institute. Following on from recent work developing graphene-silicon Schottky photodiodes,

MPhys projects 2018 - Welcome

The group welcomes four undergraduate MPhys students who will spend the semester working on their final year project: * Lily Shepherd and Rachel Clark return to work on compressive sensing applications for future photovoltaic characterization. * Jade Clarke and Eadie Weston will start a new project on open-science, looking to create 3D

New Paper - Emission Properties and Ultrafast Carrier Dynamics of CsPbCl3 Perovskite Nanocrystals

Congratulations to Ruben Ahumada-Lazo for his new paper on emission properties of perovskite nanocrystals. In his new paper, published in ACS Journal of Physical Chemistry C, he used ultrafast and high-fluence optical techniques based at the Photon Science Institute to reveal the radiative and non-radiative recombination pathways in CsPbCl3 perovskite

New Paper - Optical Study of p-Doping in GaAs Nanowires for Low-Threshold and High-Yield Lasing

Our new work on large-scale statistical spectroscopy to optimize nanowire lasers is published today in Nano Letters. In this work, PhD student Arturo studied thousands of nanowires to identify the lowest threshold nanowire, as well as to model emission to identify the primary sources of non-radiative emission. By quickly sorting

Presentation at ICYRAM-2018

Arturo gave an oral presentation on his work – “Nanolaser optimization through statistical optoelectronic analysis” at ICYRAM in Adelaide as part of a IOP Barber Fund supported conference trip.
