摘要:
本文导出在零温度条件下的零禁带半导体的介电常数的解析公式。考虑到LO声子散封的贡献说明反衬称的能量吸收峰。对光学声子和电子载流子之间的耦合也作了研究,产生的新的模是声子和电子激发的很强的混合,并讨论了这些模的一些特征。
Abstract:
The analytic formulas of the dielectric function in ZGS at zero temperature are derived. The contribution of LO phonon scattering has been taken into account to explain the asymmetric energy loss peaks. The coupling between optical phonons and carrier electrons is investigated. The new modes ore strong admixtures of phonons (polaritons) and electron excitations. Several features of these modes are discussed.
