The Effect of Interfaces on Heat Transport Mechanism of Y-Ba-Cu-O Thin Film Superconducting Bolometer, Ph.D. Dissertation Sharif University of Technology ; Vesaghi, Mohammad Ali (Supervisor) ; Fardmanesh, Mahdi (Supervisor)
Abstract
In this thesis, we are focusing on the heat transport mechanism in one of the most applicable kinds of superconducting detectors called, YBa2Cu3O7-x (YBCO) transition-edge bolometer. The Time Domain Thermoreflectance (TDTR) method is described as a tool for investigating the thermal boundary conductance and thermal conductivity of the materials, and the measured thermal conductivity of our YBCO films is reported here. Although some recent papers have shown a dependence of the thermal conductivity of the YBCO films to their thickness, our results on many samples with different substrates didn’t show the reported thickness dependency and we have obtained the thermal conductivity of the YBCO...
