Time- and momentum-resolved nanoscale thermal transport
Abstract/Contents
- Abstract
- There is a growing need for materials with non-traditional transport properties. For example in microcircuits, materials that can dissipate heat rapidly while acting as electrical insulators are sought for efficient heat sinks. Thermoelectric materials, useful for converting waste heat into electricity and for providing all solid-state (coolant-free) refrigeration, demand the exact opposite: thermal insulators with large electrical conductivities. Thus there is interest in ways to tailor the thermal transport properties independent of electrical properties. Currently ways to probe the microscopic physics underlying thermal transport in solids, however, are restricted to external mechanisms, for example contact-based transport measurements or non-contact thermoreflectance imaging. X rays on the other hand, because of their penetrating power, are able to explore the details of thermal transport below the surface. Along these lines, we developed means of using time-resolved x-ray diffraction to probe microscopic thermal transport in materials with embedded nanoparticles, across thin-film interfaces, and in working miniaturized thermoelectric devices. In this thesis we describe several experiments utilizing x rays from storage rings and free electron lasers to explore thermal transport in the time domain via the pump-probe technique.
