We developed an advanced 2ω method for thermal conductivity (κ) measurements that is also applicable to samples with a wide range of thicknesses, to which the flash method cannot be applied. The conventional 2ω method, which features a simple setu

Fe3O4 films on Si substrates have been intensively studied for the realization of resistance random access memory composed of only ubiquitous elements. The biggest issue for the application of Fe3O4 film/Si in small-scaled devices is the low Off/On r

We investigated thermal conductivity of epitaxial germanane films: stacked structure of hydrogenated germanenes. It was confirmed that single crystalline germanane films were epitaxially grown on Ge(111). The films exhibited low out-of-plane thermal
