Abstract :
Using the Wigner function to simulate semiconductor processes and depicting the results graphically is leading to new insights concerning these devices. The Wigner function, which uses a formalism that correctly incorporates all the quantum mechanics inherent in a problem, is the Fourier transform of the density matrix, taken with respect to a difference variable. The tunneling problem and the simulation of the resonant tunneling diode are discussed.<>
