Noise characteristics of ultrasmall resonant-tunneling structures

[[abstract]]We report a theoretical study of the noise properties of an ultrasmall resonant-tunneling structure. An analytical expression is derived for the noise power spectrum with the equation-of-motion method. We study the noise behavior as a function of both the bias voltage and the barrier characteristics, and find that the correlation between electrons induced by the Coulomb repulsion can suppress the noise significantly, and should be observable in a noise measurement.[[fileno]]2030120010028[[department]]電機工程學
