Nonequilibrium phenomena in adjacent electrically isolated nanostructures.
Physica E Low-dimensional Systems and Nanostructures 40 (5), pp. 995-998.
We report on nonequilibrium interaction phenomena between adjacent but electrostatically separated nanostructures in GaAs. A current flowing in one externally biased nanostructure causes an excitation of electrons in a circuit of a second nanostructure. As a result we observe a dc current generated in the unbiased second nanostructure. The results can be qualitatively explained in terms of acoustic phonon based energy transfer between the two mutually isolated circuits.
