متن کاملFrequency Dependence of Shot Noise in a Diffusive Mesoscopic Conductor
Detailed measurements of the voltage, temperature, and frequency dependence of the nonequilibrium current fluctuations for a diffusive mesoscopic conductor are reported. The data confirm predictions that a mesoscopic conductor shorter than the electron-electron inelastic length will display shot noise. Furthermore, the low temperatures (100 mK) and high frequencies (1–20 GHz) used for the measu...
متن کاملShot Noise
A recent theory is reviewed for the shot noise of coherent radiation propagating through a random medium. The Fano factor P/Ī (the ratio of the noise power and the mean transmitted current) is related to the scattering matrix of the medium. This is the optical analogue of Büttiker’s formula for electronic shot noise. Scattering by itself has no effect on the Fano factor, which remains equal to ...
متن کاملJohnson Noise and Shot Noise
Two types of electrical noise fundamental to any circuit and their relation to fundamental constants are investigated. Johnson noise of a controlled-gain system is measured across different resistances and temperatures, leading to a calculation of the Boltzmann constant k = (1.48± .07)×10−23J/K and absolute zero T0 = −(270±30) ◦C. The shot noise of a variable-current system is measured, leading...
