Investigation of Anisotropic Heat Transport Through Frequency Domain Thermoreflectance Technique
… heat transport in anisotropic materials through frequency domain thermoreflectance (FDTR) technique. Firstly, I describe the experimental setup and numerical modeling of the FDTR. Then, I explain the development of beam offset frequency domain thermoreflectance (BO-FDTR) and frequency domain …

Heat transport by phonons in crystalline materials and nanostructures
… studies presented in this dissertation are time-domain thermoreflectance (TDTR) for measurements of thermal conductivity of nanostructures and thermal conductance of interfaces; and frequency-domain thermoreflectance (FDTR), which I developed as a direct probe of the mean-free-paths of dominant …

Experimental studies of heat transport across material interfaces at the nano and micro scales
… such as MoS2 and micron scale particles. We used frequency domain thermoreflectance (FDTR) to conduct all thermal property measurements. This technique can measure thin film thermal properties as well as characterize the interface between two materials. Molybdenum disulfide (MoS2), a transition …

Phonon and electron transport through interfaces and disordered structures
… can induce coherent backscattering for low-frequency phonons and limit the contribution to transport of high-frequency phonons. The interferences among scattered low-frequency phonons lead to a peak in the thermal conductivity versus length curve, a characteristic feature of phonon Anderson …
