On Quantum Corrections to Space Charge Waves in Silicon

An analysis that incorporates quantum corrections and the thermal conductivity term into the classical hydrodynamic model of the propagation of space-charge waves in silicon is presented. From numerical simulations we have seen that for frequencies f 8THz both quantum corrections and thermoconductivity are equally important. These results suggest accurate simulations of ultra-small device require the thermal conductivity term to be included in the model.
