Cover Story (view full-size image): Thermal transport in nanolayered thin films is investigated by Time-Domain X-ray Thermal Scattering, whereby a surface transducer layer serves both as heat source and temperature probe during laser pump – X-ray probe, recording the picosecond-resolved lattice expansion. This method allows for quantifying heat flow on a Kelvin scale and additionally discerning elastic from plastic behavior. The two discussed examples include epitaxial layers with isotope modulation as well as molybdenum-silicon multiplayers representing two extreme cases for thermal conductivity control by layering.
