The condition of a stationary transport process is a common origin for the approaches for terminal current noise. Based on a recently-proposed stationary model and the integral form of the Boltzmann equation, we derive a transient stochastic process whose autocovariance function characterizes the terminal current noise. The properties and the domain of application of this transient model and its stationary counterpart are investigated. Numerical experiments are presented which support the conclusions drawn for the two models. © 2002 American Institute of Physics.
