Job announcements relevant to people interested in electronic structure calculations…
Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.
phD position: Atomistic modelling interfacial th ... (No replies)
Back to Job listings...
The phD offer is part of a national french ANR project gathering theoreticians and experimentalists all experts in nanoscale thermal transport. This project tackles innovative nanoscale phonon concepts for the optimization of the conception of nano-devices for thermal management applications. At the limits of heat management, the performance of energy conversion devices are limited by heat transfer across interfaces between metals and semiconductors. Very recent experimental studies have demonstrated the possibility to enhance interfacial heat transfer by doping the semiconductor [1]. A theoretical understanding of the different energy channels at metal/semiconductor interfaces is essential to imagine new and efficient thermal management devices. We plan to address thermal transport at metal/semiconductor interfaces using state-of-the-art atomistic calculations including molecular dynamics and ab-initio calculations.
The successful candidate should hold a Master degree in Physics, Physical Chemistry or Material Science. He/she should have knowledge and a taste for solid state physics (phonons), modeling and basic programming (fortran or C or python). Good communication skills and english writing are requested. The phD student will work at the Institute Lumière Matière (ILM) in Lyon (France), under the supervision of S. Merabia (CNRS), C. Adessi (UCBL prof.), T. Niehaus (UCBL prof.) and K. Termentzids (CNRS, CETHIL Lyon). He/she will also interact with our experimentalist colleagues all over France.
Interest candidates should send an email along with a resume and a letter of motivation to Samy Merabia ([email protected]) and Christophe Adessi ([email protected]) Informal enquiries are welcome.
