Theory, Modelling and Computational Methods for Semiconductors

Posted on 4 February 2010

University of York Physics department hosted workshop on 13-15 January 2010

The second workshop on the subject of Theory, Modelling and Computational methods for Semiconductors (known as TMCS II), hosted by the Department of Physics on 13-15 January 2010, was a great success with some 50 delegates over the three days.

Most delegates were UK based, but invited speakers from Finland (Professor Risto Nieminen of the Helsinki University of Technology) and Ireland (Professor Eoin O'Reilly of the Tyndall Institute in Cork) attended, and talks were also contributed by attendees from Rome, Vienna, Ireland and Spain.  The other invited speakers were Professor Rex Godby (University of York), Professor John Robertson (University of Cambridge) and Dr Stewart Clark (University of Durham).

A number of the international speakers originally scheduled to attend and present were unfortunately deterred by the threat of heavy snow in Yorkshire, and cancelled shortly prior to the workshop. Otherwise we would have welcomed some 60 delegates in total.

The event was sponsored by the UK Car-Parrinello Consortium, the IoP Semiconductor Physics Group and the IoP Computational Physics Group. Industrial sponsorship was provided by Accelrys Ltd of Cambridge and QuantumWise of Copenhagen, both of whom had an exhibition and presentation of their software packages.

The event was held in St William's College, in the centre of York next to the Minster.

The first day of the workshop was dedicated to student training, with four presentations (each 90 minutes long) on topics in modelling of semiconductors at a PhD student level. These covered the range of topice that were to be discussed over the next two days. These talks were well received, with around 25 attendees participating, most of whom stayed on for the main body of the workshop.

The second and third days comprised a succession of talks (invited talks 30 minutes long, contributed talks 15 minutes) covering the range of current theoretical/computational research in semiconductors, including high-level GW theory of quantum transport, applications of DFT to study defects, semi-empirical methods to study quantum dots, photonic methods to study quantum cascade lasers, etc. There were also poster sessions, hands-on practical sessions with codes from Accelrys and QuantumWise, and a conference dinner.

Full details of the programme (including copies of the talks) are available at the TMCSII website

In the closing discussions, it was decided that a TMCS-III conference should be organised in 2012, at the same time of year and with a similar format. An international advisory committee will be formed later this year to prepare the next conference.

Dr Matt Probert, of the Department of Physics, was the local organiser and also the co-chair of the event (along with  Dr Max Migliorato of the University of Manchester). The same team also created the inaugural TMCS event in Manchester in 2008.
