The QED group

The Quantum Electronic Devices group is part of the Condensed Matter department in UNSW's School of Physics in the heart of Sydney. Our research is focussed on studying the fundamental properties of low dimensional systems realised in advanced semiconductor devices, and developing new organic semiconductor and superconducting devices.

3-March-2008

Welcome to six new and old students for Session 1 in 2008. Karl Chan and Alex Szorkovsky are back for more physics Honours fun, and are joined by Jeremy Badcock. Dan Ong and Sam Yick join the group for their Nano Honours projects, and Stephan Strahl is doing an exchange program from Regensburg.

 

28-Feb-2008

Not to be outdone, Ted Martin has just had his paper "Confinement properties of a Ga0.25In0.75As/InP quantum point contact," accepted for publicaton in Physical Review B. Nice work!

 

27-Feb-2008

Congrats to Sarah for her paper on "Single particle and momentum relaxation times in two-dimensional electron systems", which has appeared in Proc. of SPIE Vol. 6800, 68001L, (2008). This is the culmination of her Honours thesis, and quite an achievement (and a small step to Dr. X's sweet, sweet office).

 

25-Feb-2008

Adam, Lasse, Ted and Oleh are in Melbourne this week to attend the 2008 International Conference on Nanoscience and Nanotechnology. Ted is giving a talk on"Coupling of electron quantum interference effects in arrays of hard-walled semiconductor cavities" and Oleh is talking about "Hole transport in undoped one dimensional quantum wires". Lasse is presenting a poster on phonon coupling in metallic wires, and Adam is organising & chairing the Australian Research Council Nanotechnology Network ECR/Postgraduate Student Symposium (as well as chairing one of the Nanoelectronics symposia).

 

11-Jan-2008

Another Paper in Physical Review Letters! "0.7 Structure and Zero Bias Anomaly in Ballistic Hole Quantum Wires" by Romain Danneau, Oleh Klochan, Warrick Clarke, Lap-Hang Ho, Adam Micolich, Michelle Simmons, Alex Hamilton et al has just been published (Phys. Rev. Lett., 100, 016403 (2008)). Congratulations to everyone!

 

31-Sept-2007

"An improved process for fabricating high-mobility organic molecular crystal field-effect transistors" by Adam Micolich, Laurence Bell (Hons. student), and Alex Hamilton has just been published in the Journal of Applied Physics, 102, 084511 (2007).

 

27-Sept-2007

New PhD projects (800kB PDF file) are available for making and studying semiconductor nanostructures to study spin-orbit coupling and spintronics applications in both electron and hole nanostructures.

 

26-Sept-2007

The QED group has done really well in this year's ARC funding, winning a 3-year $380k Discovery grant on nanospintronics, a 3-year $80K Linkage International grant and a $440k Linkage Infrastructure grant to commence in 2008.

 

15-Sept-2007

The QED group gets another paper in a high impact journal! Warrick Clarke's paper Impact of long- and short-range disorder on the metallic behaviour of two-dimensional systems has been accepted for publication in Nature Physics. NP has an impact factor of 12, so that's pretty good. But then it's a pretty good paper - well done all.

 

10-Sept-2007

Ulrich Zuelicke, our collaborator in New Zealand, wins Massey University's largest Marsden grant, NZ$800k, to study zitterbewegung - way to go Uli.
