Abstract

The results of measurements of the thermal boundary resistance (RFS) of the interface between a one-layer granular film on a substrate are presented, which reveal the relationship between the RFS value and the grain size in the film material. For a 10-nm-thick nanocrystalline (Fe0.5Co0.5)0.4Cu0.6 film deposited on a silicon substrate with a 50-nm-thick SiO2 oxide layer (interlayer), RFS is increased by almost two orders of magnitude compared to the minimum reported value (10 –7(m2K)/W). The thermal boundary resistance of a La0.65Ca0.35MnO3 film with a microcrystalline structure, which was deposited over a YBa2Cu3O7 –δinterlayer on a SrTiO3 substrate, is RFS = 10–6(m2K)/W.
