摘要：

The one-dimensional (1D) density of states (DOS) is calculated self-consistently for double-barrier quantum-well structures in the presence of a perpendicular magnetic field. With the application of a magnetic field, there is a redistribution of the 1D DOS along energy and distance. Contrary to this, an applied electric field results in redistribution mainly along the energy axis. The inclusion of the phase-breaking scattering mechanism diminishes the first peak of the 1D DOS along the energy axis. The total number of states is constant, irrespective of any external (electric or magnetic) fields or phase-breaking scattering.
