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.
The first official release of AlmaBTE is out! Check-out AlmaBTE 1.0 at the downloads page. With respect to the earlier beta version this release includes major improvements in the Monte Carlo solver and added capabilities.
A pre-release beta version of AlmaBTE can now be downloaded here. AlmaBTE is licensed under the Apache License, Version 2.0. Copyright 2015-2016 The ALMA Project Developers.
The 8th International Conference on Multiscale Materials Modeling will take place in Dijon, France, October 9-14th, 2016. Alma is co-organizing symposium B, Materials design: where condensed-matter physics and big-data informatics meet. A topical session within this symposium will be dedicated to “Multiscale electronic and thermal transport modeling of materials and devices with industrial applications”. http://mmm2016.iop.org/Symposia_BRead more about 8th International Conference on Multiscale Materials Modeling[…]
AlmaBTE has been used to predict the cross plane thermal conductivity of technologically relevant crystalline and solid solution thin films, including SiGe, InGaAs, AlGaN, and the highly anisotropic SnSe. The calculation unveils the existence of a clearly distinct regime of sub-ballistic thermal conduction with a fractional exponent in the film’s thickness dependence, occurring only onRead more about Heat conduction across thin films calculated with AlmaBTE[…]
Silvaco and the ALMA consortium partners have published a press release with information about the resources and goals of the project.
The particle-based Montecarlo solver of the Boltzmann transport equation in ALMA has reached its first important milestone after becoming able to compute the effective thermal conductivity of a slab of crystalline silicon from first principles. The figure shows how important deviations from Fourier’s law are in microscale and nanoscale devices. ALMA will afford better predictiveRead more about ALMA’s Montecarlo solver generates its first result[…]
