An unusually strong resonant phonon scattering by 3-d impurities in II–VI semiconductors
Abstract
Low temperature phonon heat conductivity was measured for ZnSe and ZnS crystals, doped with 3-d impurities. A strong resonance-like phonon scattering by 3-d ions with orbitally degenerate ground state was observed. The Jahn-Teller effect is proposed as the reason of the strong resonance-like behaviour of heat conductivity. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
