Dr. Ryou Research Group
Semiconductor Materials and Applications
Research area Our research area includes semiconductor materials and devices for photonic, electronic, and energy applications, such as light-emitting diodes (LEDs), photovoltaic solar cells (SCs), field-effect transistors (FETs), high-electron mobility transistors (HEMTs), and piezoelectric generators (PEGs) and sensors.
Research tools: Our expertise includes (1) TCAD device simulation, (2) epitaxial growth by metalorganic chemical vapor deposition (MOCVD), chemical vapor deposition, and physical vapor deposition, (3) materials characterization, and (4) device fabrication and characterization
Recent and current research topics: High-efficiency flexible photovoltaic solar cells using single-crystal-like GaAs thin film directly grown on low-cost metal tape
