Exciton Insulators

21 July 2021

We find evidence for 'Excitonic Insulators', using ultrafast pump-probe laser microscopy, in a collaboration with groups around the world.

Looking at lithium ion batteries

7 July 2021

Interferometric scattering microscopy (iSCAT) is used to look at transport processes inside batteries, in a collaboration between the Chemistry and Physics Departments. It will help us to explore the fundamental limits in charge and discharge rates in working batteries.

Doping Perovskites

10 June 2021

Manganese-doping of perovskite nanocrystals increases their luminescence yields due to an unexpected enhancement of radiative recombination rates. The results demonstrate how transition-metal doping provides precise control of electronic structure and exciton dynamics in metal-halide perovskite nanocrystals and it opens a...

Discovery of an Excitonic Insulator

22 March 2021

Dr Akshay Rao and team have looked at a new material Ta2NiSe5, with ultrafast lasers

Working at home

7 April 2020

The OE Group is currently 'working from home' in the current Coronavirus situation. This means that telephone calls direct to the Department are unlikely to be answered. However, most people are available on email, though response times might be a little slower than normal...

First Year Students present their reports - July 2019

25 July 2019

Most of the OE and ME First Year PhD students have given presentations this week on their work so far. For many of them, it is the first opportunity to give a talk to the group, and they welcome feedback from colleagues. There were quite a few 'hot topics' - and it was good to be in an air conditioned room, on the hottest...

Winterschool 2019

9 April 2019

The Optoelectronics and Microelectronics groups' 'Winterschool 2019' was a chance at the end of March to compare the energy landscape of novel materials with the ups and downs of Austrian slopes! Evening seminars covered topics such as carrier mobility, DNA structures and Quantum Dots, with fluorescent emission and light...

OE's Stuart Macpherson gets to the semifinal of University Challenge

9 April 2019

Congratulations to Stuart Macpherson, a second year student in OE, working in Strankslab . As part of the Darwin team, he has got through 5 matches (two in the Quarterfinals) to play in the semifinal against St Edmund Hall, Oxford. It will be broadcast on Monday 15th April on BBC Two.

Optoelectronics Spring School 2018

26 March 2018

At the OE Spring School, students and postdocs gave talks on a variety of subjects, with new materials and new measurement techniques playing an important part of our research. 'Perovskites' are a hot topic: they come in a variety of 'flavours', with the promise of efficient solar cells and light sources. We look at the...
