P. Shiktorov et al., ACCELERATION FLUCTUATION SCHEME FOR DIFFUSION NOISE SOURCES WITHIN A GENERALIZED IMPEDANCE FIELD METHOD, Physical review. B, Condensed matter, 57(19), 1998, pp. 11866-11869
It is shown that the spectral density of the diffusion noise source ca
n be described in terms of accelerations caused by single scattering e
vents. Within a hydrodynamic approach a response-function formalism fo
r the spectral density of voltage fluctuations in semiconductor struct
ures is developed on the basis of a generalized impedance field method
. The formalism is validated by comparison with Monte Carlo simulation
s of n-type GaAs structures. [S0163-1829(98)01316-2].
