Surface-Acoustic-Wave-Induced Transport in a Double Quantum Dot
Surface-Acoustic-Wave-Induced Transport in a Double Quantum Dot
We report on nonadiabatic transport through a double quantum dot under irradiation of surface acoustic waves generated on chip. At low excitation powers, absorption and emission of single and multiple phonons are observed. At higher power, sequential phonon assisted tunneling processes excite the double dot in a highly nonequilibrium state. …
