Thermal diffusivity of al0.3ga0.7as by molecular dynamics simulation And thermograph method

The thermal diffusivity of Al0.3Ga0.7As is studied by Molecular Dynamics simulation (MDS ). Tersoff’ s potential is used for the simulation for this alloy. Also experimentally studied here using photoacoustic method and thermography. Thermal diffusivity determined experimentally agrees well with the MD simulation and literature values /12/. The results are compared with the host GaAs.
