The almaBTE software package developed by this project extends the ShengBTE approach currently employed for homogeneous bulk materials, into the mesoscale, to fully describe thermal transport from the electronic ab initio level, through the atomistic one, all the way into the mesoscopic structure level. AlmaBTE is oriented towards industrial applications, particularly in the rapidly evolving field of GaN based power electronics, and in all new technologies where thermal transport is a key issue.
ALMA was launched in June 2015, and is funded by the European Commission through the Horizon 2020 – Research and Innovation Framework Programme, for a three year duration.

On October 23, 2017, we will hold a hands-on training session for researchers at ST microelectronics in Catania, Italy. This short course will cover almaBTE’s basics, practical use, and its application to thermal design problems in nanoelectronics.
Version 1.2 of almaBTE is now available from the downloads page. This maintenance release refines the implementation of the nonanalytic correction to the dynamical matrix and thereby provides a more accurate computation of the phonon spectrum and conductivity tensor in polar compounds.
A new version of almaBTE is now available from the downloads page. Release 1.1 includes the following changes: Improvements Reduced memory footprint of Monte Carlo solver All executables taking xml input verify the presence/existence of the input file beyondRTA routines are now parallelised Revised implementation of the non-analytic correction Bundled a newer version (3.3.3) ofRead more about almaBTE v.1.1 released[…]
It’s that time of year again to do a spot of spring cleaning. Our website has a fresh, clean look that offers a smoother reading experience and easier navigation. We also added a dedicated publications page that lists all project-related journal papers.
