Abstract
A theory of noise characteristics of a double-barrier resonant-tunneling system is established. The noise-current power density has a Lorentzian form with a characteristic frequency given by the resonance-level broadening. The low-frequency characteristics which are dependent on structure parameters and bias voltage can be directly compared with experimental measurements.Keywords
