Picosecond optical studies of amorphous diamond and diamondlike carbon: Thermal conductivity and longitudinal sound velocity

Although this study, focuses on thermal conductivities of amorphous diamond (a-D) and diamond like carbon (DLC), the same picosecond thermo reflectance data can be analyzed to yield values for the longitudinal sound velocity in the film, C sub(h). This quantity was also examined for its dependence o...

Zusammenfassung:Although this study, focuses on thermal conductivities of amorphous diamond (a-D) and diamond like carbon (DLC), the same picosecond thermo reflectance data can be analyzed to yield values for the longitudinal sound velocity in the film, C sub(h). This quantity was also examined for its dependence on film type and preparation conditions.
