Consider a material that can be altered with exposure to an electric field such that it undergoes a structural transition from an insulator (state) to an electrical conductor (state) when the field is applied. The material in both its insulator and conductor states has a phonon contribution to its thermal conductivity of ? = 2 W/m·K. What is the thermal conductivity of the material with and without an applied electric field? ( electrical resistivity is ????? = 1x10-6 m/S at ? =27C with an applied electric field)
