| Research Abstract |
We have investigated controolf electron transport in semiconductor quantum nanostructures by irradiating intense terahertz radiation. The main results are the following;1) By irradiating semiconductor superlattices with intense terahertz radiation, we have succeeded in suppressingigh-hfield domains that hinder terahertz Bloch oscillation.2) We have succeeded in controlling single electron transport by focusing intense terahertz radiation on single quantum dots through nanogap electrodes and inducingphoton-assisted tunneling.
