Description
This review is focused on the development of experimental methods for measuring thermal transport properties. Special emphasis is given to plane probes, which are used both as heat sources and as temperature recording devices. With such probes it is under certain conditions possible to determine both the thermal conductivity and the thermal diffusivity from a single transient recording. The conditions which must be fulfilled in an experiment are introduced by the use of the concept of a thermal probing depth, and from which the time window of observations can be defined. The ultimate goal of the dual determination of the thermal transport properties of a substrate is to reveal the anisotropy of the material from which the substrate should be a representative sample.
