✦ Synopsis

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.
