Introduction

  • Our research covers basically a whole range of making solid-state lighting devices including LEDs, semiconductor lasers, and other electroluminescent devices from thin film growth to final chip fabrication. Thin films for novel light-emitting devices can be made by Metal Organic Chemical Vapor Deposition (MOCVD) system.
  • Research in our lab includes not only making devices but also doing various analyses, for example, photoluminescence (PL), electroluminescence (EL), morphology investigation using scanning electron microscope (SEM) and x-ray diffraction (XRD), and so on.
