摘要：
Single-wall carbon nanotube (SWCNT) quantum dots have been fabricated on a GaAs/AlGaAs two-dimensional electron gas (2DEG) substrate, and the single electron transport measurements have been carried out at 2.8 K and 22 mK with the 2DEG used as a gate. It was demonstrated that the gating by the 2DEG could be switched on and off by controlling a quantum point contact fabricated between the dot and the Ohmic contact to the 2DEG gate. The unique combination of the SWCNT dot and the 2DEG may open a door to realize flexible hybrid devices. (c) 2005 American Institute of Physics.
