Exploring electron and phonon transport at the nanoscale for thermoelectric energy conversion
… materials are capable of solid-state direct heat to electricity energy conversion and are ideal for waste heat recovery applications due to their simplicity, reliability, and lack of environmentally harmful working fluids. Recently, nanostructured thermoelectrics have demonstrated remarkably …

Thermal and thermoelectric properties of nanostructured materials and interfaces
… parameter for the device performance. At the nanoscale, the mean free path and wavelength of heat carriers may become comparable to or smaller than the size of a nanostructured material and/or device. For nanostructured materials made from semiconductors and insulators, the additional phonon …

Nanoscale thermal transport through solid-solid and solid-liquid interfaces
… presents an experimental investigation of heat transport through solid- solid and solid-liquid interfaces. Heat transport is a process initiated by the presence of a thermal gradient. All interfaces offer resistance to heat flow in the form of temperature drop at the interface. In micro and …

Heat Transport across Dissimilar Materials
All interfaces offer resistance to heat transport. As the size of a device or structure approaches nanometer lengthscales, the contribution of the interface thermal resistance often becomes comparable to the intrinsic thermal resistance offered by the device or structure itself. In many …

Thermal transport in graphene-based nanostructures and other two-dimensional materials
Heat conduction in nanomaterials is an important area of study, with both fundamental and technological implications. However, little is known about heat flow in two-dimensional (2D) materials or devices with dimensions comparable to the phonon mean free path (MFP). Here, we investigated thermal …

Using high pressure to study thermal transport and phonon scattering mechanisms
… aerospace industry studies nanocomposites for heat dissipation and moderation of thermal expansion, and the semiconductor industry faces a Joule heating barrier in devices with high power density. Be it for the nanocomposite frame of a satellite's solar panel array, or a miniaturized high-power …

Heat transport by phonons in crystalline materials and nanostructures
… dissertation presents experimental studies of heat transport by phonons in crystalline materials and nanostructures, and across solid-solid interfaces. Particularly, this dissertation emphasizes advancing understanding of the mean-free-paths (i.e., the distance phonons propagate without being …
