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.

"Hell yeah" says Lap-hang as his paper Ground-plane screening of Coulomb interactions in two-dimensional systems: How effectively can one two-dimensional system screen interactions in another (L.H. Ho, A.P. Micolich, A.R. Hamilton and O.P. Sushkov) is accepted for publication in Physical Review B. Good work!

Jason Chen and Oleh Klochan are in Cambridge for 4 weeks to work with collaborators at the Cavendish Laboratory, and enjoy the English summer.

 

30 July 2009

The 2009 Gordon Godfrey Workshop on Spins and Strong Correlations will be held at the University of New South Wales from 26-29 October 2009, with a plethora of international speakers. See the workshop website for details.

 

19-July-2009

Adam Micolich, Oleh Klochan, Jason Chen and Lasse Taskinen are all in Japan for the week, each presenting their work at the 18th International Conference on the Electronic Properties of 2 Dimensional Systems (EP2DS-18).

 

13 July 2009

Two awards for QED researchers: Dr. Oleh Klochan wins a $3000 travel award from the ARC Nanotechnology Network to visit the University of Cambridge for a joint research project. Jason Chen is awarded a scholarship to allow him to present his work at the 18th International Conference on Electronic Properties of Two-Dimensional Systems (EP2DS-18) in Kobe, Japan.

 

 

19-Jun-2009

The work of Honours students Sarah MacLeod and Karl Chan, together with Dr. Ted Martin, has been accepted for publication in Physical Review B. It's a nice examination of impurity scattering in two-dimensional systems, showing how previous treatments have made some unphysical assumptions. With their improved approach Karl, Sarah and Ted are able to get extremely good agreement of their theory with experimental data obtained by Andrew See. Have a read: The role of background impurities in the single particle relaxation lifetime of a two-dimensional electron gas, S. J. MacLeod, K. Chan, T. P. Martin, A. R. Hamilton, A. See, A. P. Micolich, M. Aagesen, and P. E. Lindelof, accepted for Physical Review B.

 

15-Apr-2009

Another paper on 1D holes, which neatly clears up some controversies in the field, has just been published in the New Journal of Physics: "The interplay between one-dimensional confinement and two-dimensional crystallographic anisotropy effects in ballistic hole quantum wires" by O Klochan, A P Micolich, L H Ho, A R Hamilton, K Muraki and Y Hirayama. Well done all.

2-Apr-2009

The QED group has an opening for a Senior Research Associate to work on hole nanoelectronics - details are here (position now closed).

 

11-Mar-2009

Our paper "The 0.7 anomaly in one-dimensional hole wires" has been selected by the Editorial Board of the Journal of Physics C as one of the top papers of 2008, based on the number of downloads. See the special edition here, which also gives free access to the paper throughout 2009.

5-Mar-2009

Adam Micolich has won the Edgeworth David Medal, a prestigious early career award made by the Royal Society of New South Wales. The medal is awarded annually to a scientist under the age of 35 for distinguished contributions to Australian science. Previous winners include palaeontologist and former Australian of the year, Tim Flannery, and the world-leading solar cell physicist, Martin Green. Full story here.

 

8-Feb-2009

Adam Micolich has been invited to give a lecture at the 4th Advanced Materials and Nanotechnology conference in Dunedin, New Zealand. Jason Chen has also been awarded a UNSW travel scholarship to present his work at the conference.
