Johnson-Nyquist noise in narrow wires
Abstract
Description
The Johnson-Nyquist noise in narrow semiconducting wires having a transverse size smaller than the screening length is shown to be white up to frequency $D/L^2$ and to decay at higher frequencies as $ω^{-{1/2}}$. This result is contrasted with the noise spectra in neutral and charged liquids.
