【摘要】 讨论了单晶样品光吸收系数的实验测定技术和计算方法。研究了掺 Zn的 p 型 InP 单晶的近红外吸收系数与波长、载流子浓度及其霍耳迁移率的关系,得出了它们之间的经验关系。讨论了在载流子浓度为1×10₁₇～5×10₁₈cm^-3范围内对自由载流子吸收的贡献。更多还原

【Abstract】 The free-carrier absorption constants of Zn-doped InP singlecrystals have been measured at the near-infrared wavelengths.It was observedthat the absorption was controlled mainly by the optic-phonon scattering asthe carrier concentration ranged from 10¹⁷cm^-3 to 5×10¹⁸cm³.The empirical rela-tionship between the abborption constants,carrier concentration and the mobi-lty has been established.更多还原
