Investigation of the Non-Equilibrium Distribution Function of Acoustic Phonons and Thermal Conductivity of Very Thin Ge Layers
Heat conduction by phonons in bulk semiconductors [1,2] has been investigated extensively in the past. These investigations imply that the lattice thermal conductivity of a semiconductor is mainly limited by the interaction of the phonons with crystal boundaries, lattice defects, electrons and phonons (N-and U- three phonon processes ).
