“…The electron beam is focused down to a spot size of ~ 20 nm using electrostatic and magnetic lenses inside the scanning electron microscope (SEM). The main components of an EBL/SEM column are demonstrated in the Figure 5.20 [74], [75]. The electrons are generated from an electron gun that is set at a high accelerating voltage (usually 10-100 kV) to provide enough kinetic energy to the electrons.…”

Residential, commercial, and industrial lighting applications contribute to ~19% of total energy consumption worldwide. The application of more efficient sources of lighting, such as solid-state lighting (SSL) sources, could result in potential energy savings of about 65%. Current technologies employ semiconductor-based light-emitting diodes (LEDs) as the core elements of SSL devices to provide generalpurpose light in a wide range of color temperatures. However, there still exists several device level issues, such as poor material quality, low quantum efficiencies, large percentage of light being trapped, etc. These non-idealities are barriers for SSL sources replacing incandescent and compact fluorescent sources on an equivalent lumens-per-watt basis. WVU SSL research interests involve addressing device-level issues associated with III-V nitride materials, as well as optimizing the growth of materials and performance of fabricated devices. One major goal of research efforts is to provide solutions for improvement in light extraction in III-nitride-based devices Dawson for his guidance towards my thesis work. Dr. Dawson's wisdom, patience and constant encouragement are some of the reasons that have made the findings in this thesis possible.

Modeling and Analysis of Quantum Well Structures in GaN/InGaN Light Emitting Diodes Lekha Kuchipudi In recent years, there has been great research interest in the development of efficient Group III-Nitride Light Emitting Diodes (LEDs) due to the range of wavelengths covered by this material family. My graduation life in West Virginia University has been an educating and wonderful journey. I loved every moment of my grad life, which included challenging coursework, research and joyful instances with friends. It is now time to acknowledge all of the individuals and sources that have been a crucial influence throughout my graduate career. First of all, I owe my deepest gratitude to my advisor Dr. Lawrence A. Hornak, for his continuous encouragement and guidance through my master's. This thesis would not have been possible without his intellectual support and the physical resources he made available to me, that made my master's an enriching experience. All the valuable discussions and the training he provided will benefit me throughout my career. I strongly believe that my potential as a professional engineer has increased multifold during my association with Dr. Hornak. I am very much grateful to my committee members Dr. Dimitris Korakakis and Dr. Jeremy Dawson for their encouragement, technical discussions and feedback. Immense thanks to my lab mates Srinitya Musunuru, Joshua Justice, Anand Kadiyala, Vishal Narang and Sujan Kasani for their help and knowledge exchange in this project. I owe my sincere thanks and dedicate this thesis to my parents Kuchipudi Venkateswara Rao and Kuchipudi Poornima Rani, for all their support and encouragement through my childhood. I would also like to thank my aunt Sirisha Guttikonda and uncle Kishore Gonuguntla for their guidance and moral support.
