Daily update of GaN group talks and posters at IWN 2016

last modified Oct 10, 2016 12:14 PM

Many members of the Cambridge GaN group are currently at the IWN conference in Orlando. Bookmark this page for daily updates on posters and talks from our group and our collaborators!

Friday 7 Oct


After a week of talks and posters, group members relax at the conference dinner, with special guests from Walt Disney World in Orlando.




Thursday 6 Oct


The many posters presented on Wednesday from our group and collaborators are still on display; drop into the Ballroom on the Lobby Level to take a look at our recent research!


Wednesday 5 Oct


Today in IWN, Dr. Rachel Oliver will talk about the cutting-edge electron microscopy and tomography techniques used to study nitride-based microcavity structures. She'll be talking in the Camellia/Dogwood room at 8:00 am.

The group is presenting nine posters in today's session. If you are following us on LinkedIn for IWN updates, here is the list of the posters for today: PS2.05, PS2.90, PS2.93, PS2.117, PS2.143, PS2.166, PS2.167, PS2.168, PS2.169.


Also. H. Qian (C2.2.05) from Sheffield will talk about the work done in collaboration with our group on GaN-based vertical FET structure. Good luck everyone for a successful presentation!



Tuesday 4 Oct


At IWN today, make sure you catch invited talks by Prof. Colin Humphreys and Prof. Stefan Schulz in International North.


At 14:00 Prof. Humphreys will talk about the atomic structure of polar and non-polar InGaN quantum wells, which are revealed by combining different microscopy and spectroscopy methods.


Prof. Schulz will talk about the work being done in collaboration with Cambridge on InGaN at 08:30; Dr. Rachel Oliver will be the session chair.


Today, we have a total of eleven talks, including five from our collaborators. If you are at IWN and would like to catch up with our recent research, bookmark this page for speakers and talk IDs for today, and the remainder of IWN:

Markus Pristovsek (B1.2.03),
