声子散射对载流子输运特性的影响

Investigations on the phonon scattering to the carrier transport

分析了晶格振动对固体材料中载流子输运特性的影响,重点阐述了长声学波对载流子的散射作用.使用玻尔兹曼输运理论描述了弱场下载流子的输运特性,给出了使用形变势散射和压电散射机制计算载流子迁移率的详细分析和具体公式.

The interaction induced by lattice vibration to the carriers transport in solid materials is analyzed, the long acoustic wave scattering interaction is focused.Using the Bohzmann transport theory to describe the carrier transport, this paper gives the elaborate analyses and calculation formula of carriers mobility originating from the deformation potential scattering and the piezoelectric scattering interactions.
