Use the modihed Wiedemann-Franz-Lorenz law to estimate the phonon contribution to the thermal conductivity of a semiconductor at 298 K whose total thermal conductivity is 2.2 W m if the electrical conductivity is 0.4 x 10 S m ... [Pg.282]

The Wiedemann-Franz-Lorenz Law and the Linear Law connecting Thermal Resistance, Electrical Resistance, and Temperature... [Pg.61]

Experimentally it was found that at constant temperature the increase in the thermal resistance caused by deformation or formation of mixed crystals static disturbances of the lattice) is to a remarkable degree of accuracy proportional to the increase of the electrical resistance divided by the absolute temperature. If we compare the above formula with the Wiedemann-Franz-Lorenz law for pure metals,... [Pg.61]

As Peierls obtains a law for the electrical resistance in the limiting case, he concludes that the ratio of the electrical and thermal resistances does not decrease proportionally to T, but to 7, or in other words at low temperatures the Wiedemann-Franz-Lorenz quantity pjTw should not be constant, but should decrease proportionally to 7. [Pg.57]
