Education and Research Activities in the Laboratory

Our research includes the development of highly functional thin film semiconductor devices and the investigation of the physical principles linking the crystal growth, texture, and physical properties of semiconductor thin films. We employ a flexible approach to research, selecting computational, data science, and experimental approaches, including density functional theory calculations, device simulations, virtual screening of materials, thin film deposition, physical property analysis, and device fabrication. A representative outcome is the design of limiting efficiency BaSi2 solar cells using device simulation and computational material screening. By pursuing multidisciplinary research, we aim to develop researchers and engineers who are able to apply multiple approaches to issues in semiconductor devices and materials.

Research Themes

  1. Double heterojunction BaSi2 solar cells
  2. Virtual screening of materials for heterojunction design
  3. Silicide and germanide thin film deposition by close-spaced evaporation
  4. Two-dimensional group-IV nanosheet semiconductors
