Summary:
In this paper, a quantum wave filter constructed by coupling three quantum wave guides through thin barriers is analyzed. The filter is a quantum system with triple potentials in x-direction. Regarding an electron in the filter both as quantum wave and as a probabilistic particle, we describe the behavior of the electron by the Schrodinger and the Langevin equations. Solving the two equations, we found that the filter possessed bandpass characteristics and that the wave and particle nature of the electron were equivalent. We also found that an electron’s kinetic energy at which bandpass curve takes peak value depended on the width of the center well and the height of the barriers between the wells.
