研究テーマ　

  • Single photon and/or electron quantum devices using self-assembled quantum dots
  • Converts between elementary excitations in solids.
  • Quantum state transfer between photon and electron.
  • Physics of electronic and optical properties in quantum dot.
  • Physics and controll of spin or g-factor in quantum dot
  • Nano-cavity effects, photonic crystal and plasmonics
  • Photo-induced phenomena in semiconductors

研究内容

  • 2007-present

    • Chalcogenide semiconductors for novel devices and physics: solid state electrolyte, electrochemical metallization memories (ECM), super-ionic conduction of silver, fractal growth of metal filaments, photo-induced phenomena, and plasmonics.
    • Devices for quantum information technology: Fabrication and experimental measurement of single photon electron devices using self-assembled dots, nitride nanowires.

  • 2005-2006

    • Time-resolved measurement on quantum mechanically coupled exciton states in a quantum dot molecule (QDM), which is the first observation of PL decay in single QDM. We have also shown tuning of radiative recombination rate as fraction of direct exciton character is varied.

  • 2003-2005

    • Experimental and theoretical investigation of g-factor of self-assembled quantum dots. Knowledge of electron and hole g-factors, which are the coefficient connecting spin moment with magnetic one, is important to design such spin-based devices. For example, the system with a large g-factor is preferable for controlling spin-qubit while near-zero electron g-factor is suitable to design a quantum receiver. We have investigated the g-factor in self-assembled dots by single dot spectroscopy under applied magnetic field and by 8 band kp calculation. We have demonstrated experimentally and theoretically that the g-factor in InGaAs self-assembled dots can be tuned by changing the dot-size and/or by modifying strain.

  • 2003-2004

    • Time resolved photoluminescence measurement and single dot spectroscopy of vertically-stacked self-assembled quantum dots. We have observed a delay of PL due to non-resonant tunneling between the stacked dots.

  • 2002-2004

    • Fabrication and optical measurement of micromachined airbridge in which quantum dots are embedded. We have controlled the PL emission energy of the dots by using the MEMS device. This type of structure enables deformation coupling between nanomechanical mode of airbridge and a QD.
