摘要

本文介绍了超薄体(UTB) SOI mosfet中空穴迁移率的实验研究,涵盖了T/sub SOI/(在/spl sim/3.7 nm和/spl sim/50 nm之间)和温度(在/spl sim/79 K和/spl sim/320 K之间)的宽范围。提出了由空间约束引起的导带电位扰动引起的最薄样品表面粗糙度散射机制。

Examination of hole mobility in ultra-thin body SOI MOSFETs
This paper presents an experimental examination of hole mobility in ultra-thin body (UTB) SOI MOSFETs, covering wide ranges of T/sub SOI/ (between /spl sim/3.7 nm and /spl sim/50 nm), and temperature (between /spl sim/79 K and /spl sim/320 K). This paper addresses the observed strong degradation of hole mobility at extremely thin T/sub SOI/, proposing an additional surface roughness scattering mechanism for the thinnest samples due to the perturbation of the conducting band potential stemming from spatial confinement.
