We have generalized the model of the surface noise taking into account the self-consistent electrostatic interaction and transverse electron transport in a conductive channel. Analyzing this model, we have found that the Coulomb correlations between trapped and conducting electrons considerably suppress the surface noise. The suppression effect is shown to be frequency dependent and especially large for noisy conducting channels. © 2001 American Institute of Physics.

    Two important observations when the onset of spacecraft surface charging occurs are (1) the electron flux measured in the high-energy (above several keV) channels onboard rises and (2) the ambient electron temperature rises above a critical value.

    Although doping of a conjugated polymer by electron acceptors strongly facilitates exciton dissociation into geminate pairs of carriers, the yield of free carrier photo-generation can be high only at high doping levels, that is, in polymer/acceptor blends. We suggest a model that explains how...
