Abstract: A stationary quantum energy-transport model for semiconductors was studied in a one-dimensional bounded domain. The existence of classical solutions was proved in the case that the heat conductivity depends on the electron density and the electron temperature. Moreover, the uniqueness of the solutions was shown when the lattice temperature was large enough and the current density was relatively small. The proof was based on using an exponential variable transformation, the Leray-Schauder fixed-point theorem and some inequality techniques.

Key words: quantum energy-transport model, existence, uniqueness, stationary solutions
