Abstract
A numerical study of the dispersive limit of the quantum hydrodynamic equat ions for semiconductors is presented. The solution may develop high frequen cy oscillations when the scaled Planck constant is small. Numerical evidenc e is given of the fact that in such cases the solution does not converge to the solution of the formal limit equations.
