8th International Conference on Multiscale Materials Modeling

8th International Conference on Multiscale Materials Modeling

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[…]

Heat conduction across thin films calculated with AlmaBTE

Heat conduction across thin films calculated with AlmaBTE

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[…]

AlmaBTE’s anharmonic module passes its first test

The anharmonic module which lies at the core of AlmaBTE has passed its first test: being able to reproduce the thermal conductivity of bulk Si as a function of temperature. The physical formalism in this module is derived from AlmaBTE’s team’s previous experience in implementing ShengBTE. Although still lacking some of the postprocessing features ofRead more about AlmaBTE’s anharmonic module passes its first test[…]
