| Research Abstract |
Based on quantum dots as an ultrasensitive electrometer and the energy scales associated with carbon nanotube dot being in the teraherz(THz) range, we have studied unique THz responses of the carbon nanotube quantum dots. We have observed the THz photon assisted tunneling(THzPAT) in the single quantum dot. Fabrication processes of the coupled quantum dots have been developed and the preliminary results of the THzPAT were also observed there. The single electron transistors were also fabricated on the GaAs/AlGaAs 2 dimensional electron gas(2DEG) substrate, and the unique THz detection mechanism was observed.
