[交流] 上传一篇加州理工博士论文"Thermal Properties of Nano- and Microstructures“

(2004年)
Abstract

My work is on the experimental study of  thermal conduction in nano and microscale structures. The work is divided into two parts. In the first part, we measure the thermal conductance of a suspended device from 4 to 40 K. The thermal conduction of a suspended, free-standing beam is analyzed to study the effect of phonon scattering on thermal conduction. We conclude that phonon scattering is much more severe in a nanoscale beam than bulk material.

In the second part of the work, we proceed to dynamic measurement to measure the heat capacity of a suspended device. From that we study the origin of heat capacity of a silicon nitride membrane. We conclude that much of the heat capacity comes from the motional tunneling states of the ions. We use the device to demonstrate an ultrasensitive calorimeter with a very high resolution of 0.5 aJ/K. We conclude the work by applying the calorimeter to study the heat capacity of a thin adsorbed film of helium gas.

在这样的时侯,常引起一种空想,觉得如在江村小屋里,靠玻璃窗,烘着白炭火钵,喝清茶,同友人谈闲话,那是颇愉快地事。
