  • The intrinsic efficiency of electrocaloric materials has been largely overlooked. Here, the authors use the parameter materials efficiency as the figure of merit to rank caloric materials, reporting on the materials efficiency of highly ordered bulk lead scandium tantalate PST.

  • When thermal fields in semiconductors approach the submicron scale, non-diffusive heat transport is observed where Fourier based heat transport models fail. Here, the authors use thermal imaging to visualise these thermal field variations and in turn derive a hydrodynamic heat transport model.
