| Research Abstract |
In this study, we tried to investigate the thermal boundary resistance of nanoporous metals by measuring the phonon reflection at the nanoporous-metal/liquid-He interface. The project encountered unexpected troubles such as malfunctions of the cryostat, relocations of the laboratory, and the precedence problem of the He recovery system, etc, and the many topics have been left unclarified. We, however, obtained some results from related researches.
(1) we have carried out break simulations and studied the formation of the single-atom contact of Mg and Fe.
(2) we have measured the conductance histogram of Ni contacts and found that the single-atom peak disappears around 50K.
