Ram Chandra Subedi

PhD Students

Introduction

Ram Chandra Subedi (RC) has joined Photonics Lab at KAUST in the fall of 2016. He received his BSc and MSc in Physics from Tribhuvan University, Nepal in 2009 and 2011 respectively. In addition, he received his MS in Experimental Condensed Matter Physics University of Georgia, Athens (UGA in 2016. During his stay at UGA, he worked as a Teaching/Research Assistant. His research at UGA was primarily focused polymer/ small molecule based Organic Light Emitting Diodes (OLEDs) and Organic Spin Valves (OSVs).  Also, he has been teaching high school/ undergraduate level Physics/Math courses for a decade now. Deep UV optoelectronic devices based on III-nitride is the main focus of his research.

Research Interests

  • Semiconductor/Solid State Physics
  • Deep UV optoelectronic devices utilizing ultra-thin quantum disks
  • Bio-inspired luminescent material, 2-D materials and photonic crystals
