Nonlinear properties of ballistic quantum dot under influence of microwave radiation

ORAL

Abstract

Microwave rectification and effects of microwave radiation (1-40 GHz) on electron DC transport through a ballistic quantum dot are studied experimentally at electron temperature down to 0.3K. The experiments demonstrate significant contribution of the ballistic electron motion to the observed nonlinearities.
