About this Research Topic
Thermal transport in nanosystems is an expanding research field at the cutting edge of physics, material science and engineering. The rationale behind this novel research field consists in the significant differences of the thermal properties observed in the systems when their dimensions are scaled to the nanometer regime.
From a technological point of view, thermal management has become one of the main issues preventing a further reduction in the size of nanodevices. Moreover, nanoscale thermal transport plays a crucial role in several types of devices, such as thermoelectrics and thermal diodes.
In the last few years outstanding advancements have been achieved both in the experimental and theoretical understanding of thermal transport across a variety of interfaces, systems of reduced dimensions, crystalline and disordered, and collective phonons. However, there are still many issues that need to be further explored.
This Research Topic will present the most recent advances in this field with the aim of strengthening our understanding of heat transport both from a theoretical and experimental perspective. In particular, focus on the microscopic mechanisms governing thermal properties of different materials will be presented. This includes atomistic modeling of phonon transport, phonon–phonon interactions, and manipulation of tailored nanoscale materials. From the experimental point of view, we will present results on experimental characterization of thermal properties in real systems and impact of real materials on device perfomances.
We seek for contributions covering recent progress on fundamental aspects, applications and development of novel metrology tools relevant to the thermal properties of nanosystems. Experimental and theoretical contributions are equally encouraged. Both original research articles, in the form of full papers or communications, and reviews are welcome.
