Welcome to Kondo-lab！

We are conducting research on materials with potential applications in semiconductor photonics from film deposition to device fabrication and evaluation, making full use of film formation methods that can fabricate high-quality semiconductor crystals.

Our research focuses on crystal growth, thin-film growth, and photophysical properties of metal halide perovskite semiconductors, which are promising thin-film solar cell materials with high efficiency and large area potential. Current main research topics are as follows

  • Preparation of metal halide perovskite and heterostructure thin films by co-evaporation
  • Study of photophysical properties of metal halide perovskite mixed crystals
  • Solar cells based on metal halide perovskite thin films
  • Nonlinear optical effects and quantum mechanical photocurrent in perovskite ferroelectric semiconductors
  • Terahertz wave generation from organic ferroelectrics and ferroelectric domain visualization
