Abstract

Abstract : Precise control of thermal conduction of nanowires, both magnitude and direction, has been demonstrated, providing novel access for nanoscale thermal manipulation. Abstract : Thermal manipulation in nanowires (NWs) is of great significance for NW-based applications in the area of heat management and energy harvesting. Here, we experimentally demonstrate thermal conductivity manipulation and thermal rectification in π-stacked metallophthalocyanine (MPcs) NWs. By electron beam (E-beam) irradiation with a controllable dose, the thermal conductance of MPcs NWs can be continuously tuned to the desired values. Three thermal rectifiers were further tested on crystal–amorphous heterostructures and the thermal rectification was found to be 3.3% with a temperature bias of 10 K when T = 40 K, which is consistent with COMSOL simulations.
