New Paper - Effect of size on the luminescent efficiency of perovskite nanocrystals

A new paper led by groups at Cambridge has been published in ACS Applied Energy Materials. In this work, a combination of nanoscale cathodoluminescence and time- and energy-resolved photoluminescence is used to reveal energy dynamics in colloidal perovskite nanocrystals. These techniques relate trap density and Auger effects to stoichiometry and

Welcome to Tom Flavell

A welcome to Tom Flavell, a new PhD student in Physics who is primarily supervised by Prof. Wendy Flavell (no relation) and co-supervised by Patrick and Dr Andrew Thomas. Tom will be working on perovskite quantum dots, and will make use of the low-light spectroscopy facilities based in the OMS

New Paper - Threshold reduction and yield improvement of semiconductor nanowire lasers via processing-related end-facet optimization

Arturo has had a paper accepted for publication in Nanoscale Advances, describing the impact of the transfer process on the morphology and threshold of semiconductor nanowire lasers. While many studies have sought to improve the threshold for lasing in semiconductor nanowire lasers, the role of process has not been significantly

Workshop on Perovskites and Emerging Optoelectronic Materials

Thanks to all of the speakers and attendees who came to the Workshop on Perovskites and Emerging Optoelectronic Materials , hosted in the Photon Science Institute. We heard from 8 speakers covering physics, materials and electronic engineering for photovoltaic and light-emitting applications. The workshop was concluded with a seminar presentation from

Welcome to Harry and Lydia!

The group welcomes Harry and Lydia, two Manchester Physics MPhys students to the group. They will work together on a project to develop a high-resolution and low-cost interferometric distance standard using atomic transitions in lanthenide glasses.

Welcome to Ruqaiya and Nawal!

The group welcomes Ruqaiya and Nawal as two new PhD students working in the group. Ruqaiya will be working on nanolasers for on-chip photonics using both nanowires and nanoshapes developed by collaborators in UCL, ANU and China. Nawal will be working on ultrafast photodetectors based on 2D materials with collaborators

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

Nawapong Unsuree has had a paper accepted for publication in 2D Materials. coming from a collaboration between the Echtermeyer group (Manchester) and the Parkinson group. The research was conducted in the National Graphene Institute and the Photon Science Institute. This new research reports the application of infrared scanning photocurrent microscopy

Talk at UK Semiconductors 2019

Group PhD student Stefan Skalsky gave a talk at the UK Semiconductors meeting in Sheffield. His talk, on “Nanosecond lasing and mm-scale optical coherence length in GaAsP/GaAs Quantum-Well Nanowire Lasers” descibed his recent work using interferometric time-resolved spectroscopy to reveal the end-facet reflectivity in nanowire lasers.

PSI Seminar - Antonio Hurtado

The group welcomed Dr Antonio Hurtado of the University of Strathclyde Institute of Photonics to give a seminar at the Photon Science Institute. He spoke on Neuromorphic Photonics – the use of lasers as non-linear elements in a neuromorphic system.
