ALMA’s Montecarlo solver generates its first result

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[…]

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[…]
