Abstract
Activation processes for a two-level fluctuator (TLF) situated in a metallic nanometer-sized constriction and producing telegraph resistance noise are considered for the case of large enough biases. It is shown that these processes are dominated by TLF interaction with nonequilibrium phonons emitted in the constriction rather than with electrons (as it was suggested earlier). The asymmetry of the noise with respect to the sign of the bias observed in experiments is explained to be as the result of a corresponding asymmetry of the nonequilibrium-phonon distribution.
