| Research Abstract |
We have fabricated lateral electron tunneling structures by forming nanogap electrodes directly contacting single self-assembled InAs quantum dots (QDs) grown on GaAs surfaces. The fabricated junctions showed single electron tunneling behaviors and exhibited clear shell fillings. When quantum mechanical coupling between electrons in the QDs and the electrodes was strong, the Kondo effect was observed up to the very high temperature of T_K～80K.
Owing to the good compatibility of InAs QDs with metals, further functionalities can be added to the structure by using superconducting or ferromagnetic nanogap electrodes.
