摘要

本研究利用栅极电阻测温技术对SOI纳米线mosfet在300 K至4.2 K环境温度下的自热进行了实验评估。提取通道区域的温升，得到差分热阻，并将其绘制为器件温度的函数。尽管单个纳米线的功耗较低，但工作温度的降低导致通道内的温升从室温下的6 K左右增加到低温范围内的53 K。纳米线中的热阻比宽通道器件中的热阻低得多，尽管在极低的器件温度下，两种类型的晶体管的差热阻都会突然增加。

Experimental extraction of self-heating in SOI nanowire MOSFETs at cryogenic temperatures

This work presents an experimental assessment of self-heating in SOI nanowire MOSFETs in ambient temperatures ranging from 300 K down to 4.2 K using the gate resistance thermometry technique. The temperature increase in the channel region is extracted, and the differential thermal resistance is obtained and plotted as a function of the device temperature. Despite the lower power dissipated by a single nanowire, the operation temperature decrease causes the temperature rise in the channel to increase from around 6 K at room temperature up to 53 K in the cryogenic range. The thermal resistance is considerably lower in nanowires than in wide-channel devices, although both types of transistors present an abrupt increase in the differential thermal resistance at extremely low device temperatures.
