Our mission is to control quantum states in low dimensional semiconductors and to creat new devices and measurement techniques.
Quantum Physics in Semiconductors
We study quantum electron transport in micro/nano-meter scale devices, particularly in semiconductor quantum dots (QD), quantum wells (QW) and two-dimensional electron systems (2DES) at high magnetic fields (QHE device). Based on quantum transport phenomena, we attempt to manipulate electron waves, electron/nuclear spins and terahertz photons.
The following topics are promoted
*Electron spin manipulation: ESR of the spin-polarized edge states
*THz photon detection: QD based single electron transistors
*THz photon creation: Landau-level emission in the edge states
*THz photon transmission/confinement: THz split ring resonators
*Photo response of double QW transistors in strong magnetic fields
*Landau-level emission from Graphenes
*Inter-edge-state scattering in InGaAs 2DES
We also develop new THz or Acoustic measurement techniques for practical applications.
*Passive THz microscope: Living-cell thermal monitoring
*Acoustically stimulated electromagnetic response: Medical and nondestructive evaluation
