Time-domain thermoreflectance (TDTR) is a well-established pump–probe method for measuring thermal conductivity and interface conductance of multilayers. Interpreting signals in a TDTR experiment requires a thermal model. In standard front/front TDTR experiments, both pump and probe beams typically irradiate the surface of a multilayer. As a result, existing thermal models for interpreting thermoreflectance experiments assume that the pump and probe beams both interact with the surface layer…

Pump-probe measurements of the thermal conductivity tensor for materials lacking in-plane symmetry.

The mathematics of time-domain thermoreflectance is extended so that data reduction can be performed on non-transversely isotropic systems and a Nb-V alloy is demonstrated as a low thermal conductivity TDTR transducer layer that helps improve the accuracy of in-plane measurements.

Probing anisotropic heat transport using time-domain thermoreflectance with offset laser spots.

An analytic solution is derived for the time-domain thermoreflectance signal that occurs using non-concentric pump and probe beams on multilayer anisotropic materials and it is found that for samples where in-plane heat diffusion distances are comparable to the spot size, the signal is sensitive to in- plane heat transport.
