摘要

本文介绍了ZnO和SiC-6H晶体在红外光谱区的反射系数的研究结果。我们考虑了成对耦合的三个子系统的振动，即:(i)电磁波，(ii)光学晶格振动和(iii)自由电荷载流子的等离子体振荡。结果表明，声子和等离激子的各向异性导致了耦合振荡谱和透明区谱的一些特性。

Effect of the plasmon-phonon coupling anisotropy on the reflection coefficient of polar semiconductors ZnO and SiC-6H

We present some results of our investigations of the reflection coefficient in the IR spectral region for ZnO and SiC-6H crystals. We account for vibrations of three subsystems that are coupled in pairs, namely: (i) electromagnetic waves, (ii) optical lattice vibrations, and (iii) plasma oscillations of free charge carriers. It is shown that anisotropy of phonons and plasmons leads to a number of peculiarities in both the spectrum of coupled oscillations and transparency regions.
