Simulation and Experimental Realization of a Nano-scale Thermal Cloak.

ORAL

Abstract

Manipulation of heat flow at microstructures plays an important role in modern industry, especially for electronic and optoelectronic devices, for their performance and reliability are highly temperature dependent. Analogous to the invisible cloak in transformation optics, the thermal cloak can hide objects from heat and realize isothermal region in transformation thermodynamics. However, due to the macro-scale thermal properties may not be suitable for nano-materials, the realization of the nano-scale thermal cloak highly relies on the thermal transport in nanostructures. Here, we report our recent work of the realization of nano-scale thermal cloak based on the thermal property study of nano- materials via a spatially resolved thermal resistance measurement technique. The simulation and experiment verified its maintenance of isothermal region and heat protection capabilities. This work may provide a new way to manipulate heat transport in nano-scale devices..
