Abstract
Phonon scattering experiments of various types in cubic semiconductors doped with deep effective mass acceptors indicate an extra resonance scattering at some meV. We show, using Green's function and transformation techniques that these resonances are due to a dynamic Jahn-Teller effect of the Ɖ8-acceptor ground state. Their influence onto the thermal conductivity is calculated in terms of a specific single mode relaxation time
