| Abstract(in English) | New possibility of carbon nanotube (CNT) quantum dots (QDs) have been shown by combining hem with a GaAs/AlGaAs 2-dimensional electron gas (2DEG). For the start, we have fabricated the quantum dot (single electron transistor) on the 2DEG substrate, and demonstrated the single electron transistor operation with the 2DEG used as a gate. Besides, it was demonstrated that the gating to the CNT-QD could be controlled by pinching off the quantum point contact that was located between the contact to the 2DEG and the CNT-QD. The technique may be useful for the readout of the quantum state of the CNT-QDs that may be used for quantum computing and quantum dot cellular automata, and the impedance transformation of the CNT single electron transistor by combining it with the HEMT (High Electron Mobility Transistor). |
