Gallium Oxide Optoelectronic Devices

The GOOD webinar series is back, featuring even more rising stars of the Ga2O3 world!

We have another fantastic line of speakers promising epic discussions: Iuliia Zhelezova, Dave Rogers, Jacqueline Cooke, Dhanu Chettri, Sierra Seacat and Hartwin Peelaers.

The first session will be from Iuliia Zhelezova (University of Helsinki) presenting on “Vacancy defects in as-grown/proton irradiated and UID/Si-doped β-Ga2O3 single crystals“.

Date: Wednesday 12th February, 2-3 pm

Everybody is welcome!

The GOOD group has been putting together a programme of free webinars on Ga2O3. This first edition features a line of fantastic speakers: Piero Mazzolini, Ta-Shun Chou, Manuel Alonso Orts, Filip Gucmann and Daniel Carrasco Madrigal.

Everyone is welcome to join!

Register for the first event of the series: Piero Mazzolini on “Annealing effect on shallow and deep level defects in κ-Ga2O3 thin films“

David and Mugove were at European Materials Research Society (E-MRS) 2023 meeting in Warsaw. Lots of interesting discussions on defect characterization, methodologies, and promising applications for Ga2O3.

Arrived at the University of Warsaw for the start of an exciting week the E-MRS fall meeting.
Later today I’ll be presenting out work on studying how light is absorbed Gallium Oxide at sub-bandgap energies pic.twitter.com/PnUxJm5MCi

Lots of exciting discussions yesterday at our poster on sub-bandgap absorption in Ga2O3 at the E-MRS meeting.

Later today I’ll be back at the poster session, demonstrating how we can use the broad, defect mediated absorption properties for water quality monitoring applications pic.twitter.com/XNZL4sSEjT

Great talk by Mugove at the @europeanmrs shining a light on the effect of dislocations on the luminescence spectra of alpha Ga2O3 pic.twitter.com/Kkm4u9xPlT

David wins best student presentation at the Ultra-Wide Bandgap Oxides workshop in Bristol, for his presentation on “Hydrogen-related 3.8 eV luminescence in alpha-Ga2O3”. Well done David!!!

Great day in Bristol today talking about all things Gallium Oxide at the Ultra Wide-bandgap oxides conference. Topped off by being awarded the prize for best student presentation 🥳 pic.twitter.com/ca5MrwcOnM

Today is a great day in the history of the group, David got his first first-author paper published (https://doi.org/10.1063/5.0135103). Well done David!

Delighted to share my first first-author paper 🥳

Here we use Temperature-dependent photoluminescence to reveal a 3.8 eV emission line in alpha phase Ga2O3 that exhibits a strong dependence with Hydrogen concentration and temperature.@PhysicsStrath https://t.co/WcaYZNas2K pic.twitter.com/YALwzG6y1r

Fabien was in Bristol 5-6 January 2023 for the UK Nitride Consortium, where he delivered the Foxon lecture (opening plenary talk). He presented the recent work from the GOOD group on investigation of the nanoscale properties of GaN and Ga2O3.

So excited to give the Foxon lecture today at UKNC in Bristol!

Fabien and David were attending the International Workshop on Gallium Oxide (IWGO) in Nagano, Japan.

Followed by some french dude with what appears to be an equally epic poster reviewing metal contacts in Ga2O3.

We were at the Institut Francais d’Ecosse in Edinburgh for a Springboard meeting between Ecole Centrale de Lyon and the University Strathclyde to lay out future directions of research on UV photodetectors.

@AmbascienceUK & @BritishCouncil hosted researchers this week at @ifecosse ??????? to work on a project aiming to use new alloys for UV photodetectors⚙️

Ross receives a prestigious Vacation Scholarship from the Carnegie Trust to sponsor his summer project in the GOOD group. Congratulations Ross!

Fabien was one of the 37 researchers being awarded a Research Award from the Royal Society of Edinburgh.

Congratulations to SUPA’s @CCochard3 @UoD_physics and @FabienMassabuau @PhysicsStrath for winning RSE Small Research Grants ? https://t.co/3F6UglIy3v
