Abstract: Thermal contact resistance (TCR) has been a hot topic in electronics cooling and cryogenic superconducting thin films etc. In this paper, the fundamental research method, metrology macro- and nanotechnology and the diminishing method of TCR were discussed. The reported research suggests that in order to investigate the mechanism of TCR, the scattering and radiation of phonon and electron should be considered besides the quantitative analysis in macro. In the experiment, the current measurement accuracy is not perfect enough, the experimental work remains to be further improved. For reducing the contact resistance, in addition to the commonly used methods, producing new high-performance thermal conductivity materials (such as carbon nano-tubes) on the contact surface is a useful way. Based on summarizing the reported studies, the future research directions are pointed out.
