Simultaneously measured cross-plane thermal conductivity of Al film, Cr film and SiO2 substrate, and interfacial thermal conductance of Al/Cr and Cr/SiO2 interfaces
Interfacial thermal conductance of Al/Cr interface is much larger than that of Cr/SiO2 interface
Cross-plane thermal conductivity of Al film and Cr film is much smaller than their corresponding bulk value
Uncertainty of measured parameters analyzed by Monte Carlo method and corresponding error range obtained
