High-Density Utilization of Renewable Energy Technology
- Development of super-high-efficiency multi-junction solar cells
- Bulk growth of wide band gap materials for power devices
- Ab initio-based approach to structural stability of compound semiconductor surfaces
We are studying the growth dynamics and mechanisms of semiconductors such as III-nitrides and III-V-N materials. We investigate how these semiconductors for super-high-efficiency solar cells and power devices grow through experimental and theoretical approach. We focus on both the macroscopic phenomena using experiments and the microscopic phenomena using atomic-scale simulations during semiconductor growth processes.
