Interaction between carbon nanotube quantum dots with electromagnetic waves

基于量子点作为超灵敏静电计，碳纳米管量子点的能量尺度在太赫兹（THz）范围内，我们研究了碳纳米管量子点独特的THz响应。我们在单量子点中观察到了太赫兹光子辅助隧穿效应。已经开发了耦合量子点的制备工艺，并且在那里也观察到了THzPAT的初步结果。在GaAs/AlGaAs二维电子气（2DEG）衬底上制备了单电子晶体管，并观察到了其独特的THz探测机制。

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.
