Thermal conductivity spectroscopy technique to measure phonon mean free paths.
Size effects in heat conduction, which occur when phonon mean free paths (MFPs) are comparable to characteristic lengths, are being extensively explored in many nanoscale systems for energy applications. Knowledge of MFPs is essential to understanding size effects, yet MFPs are largely unknown for most materials. Here, we introduce the first experimental technique which can measure MFP distribu...
متن کاملThermal characterization of ZnO-DMSO (dimethyl sulfoxide) colloidal dispersions using the inverse photopyroelectric technique.
Nanofluids, i.e., colloidal dispersions of nanoparticles in a base liquid (solvent), have received considerable attention in the last years due to their potential applications. One attractive feature of these systems is that their thermal conductivity can exceed the corresponding values of the base fluid and of the fluid with large particles of the same chemical composition. However, there is a...
متن کاملThermal conductivity of bulk and monolayer MoS2
We show that the lattice contribution to the thermal conductivity of MoS2 strongly dominates the carrier contribution in a broad temperature range from 300 to 800K. Since theoretical insight into the lattice contribution is largely missing, though it would be essential for materials design, we solve the Boltzmann transport equation for the phonons self-consistently in order to evaluate the phon...
متن کاملGeothermal Potential Assesment of Way Ratai Area Based on Thermal Conductivity Measurement to Measure Thermal Properties of Rocks
Thermal conductivity measurements have been used for the Way Ratai geothermal prospect area. The thermal conductivity method is used to evaluate the ability of a rock to deliver heat by conduction. In the area, many surface manifestations are scattered in various regions, where hot springs dominate these various manifestations. The thermal conductivity mapping of rocks is carried out around geo...
متن کاملPhotoacoustic Technique for Thermal Conductivity and Thermal Interface Measurements
The photoacoustic (PA) technique is one of many techniques for characterizing thermal conductivity of materials, including thermal interface conductance or resistance. Compared with other techniques, the PA method is relatively simple, yet is able to provide accurate thermal conductivity data over a wide range of materials and properties. In the last decade, the PA method has been developed and...
