Abstract
Approximate solutions to the quantum drift-diffusion model for semiconductors are found with the aid of the symmetry group analysis. The system is written as singularly perturbed equations which are solved up to first order in the scaled reduced Planck constant. An example of solution of a nanoscale n+-n junction is provided and the difference with the classical case is shownFile in questo prodotto:
