Method for measuring contacting thermal resistance of one-dimensional structures

摘要

A method for measuring a contacting thermal resistance of one-dimensional structures is provided. A first one-dimensional structure and A second one-dimensional structure are crossed and in contact with each other to form a suspended junction. A point P of the first one-dimensional structure is heated until the first one-dimensional structure and the second one-dimensional structure reach a thermal equilibrium. A point A and a point B are selected on the first one-dimensional structure and a point C and a point D are selected on the second one-dimensional structure, wherein the point B, the point A, the suspended junction, the point C and the point D are arranged equidistantly with a distance Deltax. A temperature difference DeltaTj is calculated by the formula DeltaTj=DeltaTAC-DeltaTBA-DeltaTCD. The heat flux Qj is calculated by the formula Qj=2kDeltaTCD/Deltax. The contacting thermal resistance Rj is calculated by the formula Rj=DeltaTj/Qj.
