Abstract:The limitation of heat conductivity in cryogenic sensors due to surface roughness was discussed. It was found that at macroscopic scale and high temperatures, the transport coefficients were characteristic properties of the material and were independent of the shape and size of specimen. An experiment was demonstrated to indicate the size dependent effects. The estimation of the performance of cryogenic sensor by solving the non-linear heat equation was also elaborated.
