1.In semiconductor related research, this group uses one MOCVD and two MBE reactors for the studies of crystal growth, material and optical characterizations, and device fabrication for solid-state lighting and solar cell applications. Recent breakthroughs include the successful fabrication of high-quality, phosphor-free, white-light light-emitting diodes (LEDs) using the invented prestrained MOCVD growth technique.2.In nano-photonics research, this group focuses on surface plasmonics for energy technology and bio-sensing applications. Recent breakthroughs include the successful fabrication of LEDs with output intensity enhanced by surface plasmon coupling.3.In bio-photonics research, the major goal is to build a handy optical coherence tomography (OCT) system and associated probes for early diagnosis of oral cancer. Currently, two OCT systems have been delivered to National Taiwan University Hospital for clinical use.
