Measuring Phonon Mean Free Path Distributions by Probing Quasiballistic Phonon Transport in Grating Nanostructures
Heat conduction in semiconductors and dielectrics depends upon their phonon mean free paths that describe the average travelling distance between two consecutive phonon scattering events. Nondiffusive phonon transport is being exploited to extract phonon mean free path distributions. Here, we describe an implementation of a nanoscale thermal conductivity spectroscopy technique that allows for t...
متن کاملPhonon Transport in Nanostructures
Recent experiments aiming to produce TiO2 nanostructures have been riddled with complications. It has been found that an undesired reaction occurs with the water used in the flaking process producing a sulphurous smell. This product suggests the production of TiOxS2−x in the layered crystal structure. This nanostructure has great potential benefits for the construction of semiconductor devices ...
متن کاملDetermining phonon mean free paths from observations of quasiballistic thermal transport.
The mean free paths (MFPs) of thermal phonons are mostly unknown in many solids. Recent work indicates that MFPs may be measured using experimental observations of quasiballistic thermal transport, but the precise relationship between the measurements and the MFP distribution remains unclear. Here, we present a method that can accurately reconstruct the MFP distribution from quasiballistic ther...
متن کاملLength Dependent Thermal Conductivity Measurements Yield Phonon Mean Free Path Spectra in Nanostructures
Thermal conductivity measurements over variable lengths on nanostructures such as nanowires provide important information about the mean free paths (MFPs) of the phonons responsible for heat conduction. However, nearly all of these measurements have been interpreted using an average MFP even though phonons in many crystals possess a broad MFP spectrum. Here, we present a reconstruction method t...
متن کاملAn electrical probe of the phonon mean-free path spectrum
Most studies of the mean-free path accumulation function (MFPAF) rely on optical techniques to probe heat transfer at length scales on the order of the phonon mean-free path. In this paper, we propose and implement a purely electrical probe of the MFPAF that relies on photo-lithographically defined heater-thermometer separation to set the length scale. An important advantage of the proposed tec...
