Özet

Wigner pseudo-density functions of an electron moving in a one-dimensional sinusoidal potential in phase-space have been obtained. By an appropriate choice of the parameters related to the periodic potential the localized and free electron Wigner functions are separately constructed and they are interpreted in terms of band structure. It is observed that the negatively weighted regions in the Wigner phase-space distribution functions correspond to the forbidden zones, in which finding the particle is improbable.
