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 bar rier 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.
