Computational Study of Perovskite Structured CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> and CH<sub>3</sub>NH<sub>3</sub>SnI<sub>3</sub>
摘要： Nowadays, Hybrid Perovskite materials perform a major role in solar cell industry due to their superior power conversion ability. CH3NH3PbI3 is the prominent material in hybrid perovskite, where they comprised with advanced photovoltaic properties. But considering the toxicity, it’s more important to observe the role of metal atom in hybrid perovskite. Therefore, this research is basically focused on the objective of figuring out the fundamental properties of CH3NH3PbI3 and CH3NH3SnI3 with the idea of replacing Pb to Sn in future. Ab-Initio Simulation has been used throughout this research along with basic density function theories (DFT) like Exchange correlation functional, Local-density approximation of Kohn-Sham theory. Moreover, the research was also focused upon the Energy band gap variation, crystallographic orientations, density of states in P, S orbitals of cubic and tetragonal phases in CH3NH3PbI3 and CH3NH3SnI3.

Applied Nanophotonics || Electrons in potential wells and in solids
摘要： Absorption and emission of light by atoms, molecules, and solids arise from electron transitions. When in a potential well, an electron has discrete energy spectra; when in a periodic potential it has energy bands separated by gaps. This chapter presents an introductory overview of electron con? nement phenomena and electron properties of crystalline solids. A summary of the data for real semiconductor materials used in photonics is provided.

Fundamentals of Electroceramics (Materials, Devices, and Applications) || Elements of A Semiconductor
摘要： Semiconductor materials dominate modern electronics and microelectronics technology and have greatly influenced our civilization. Their impact is second to none in each and every aspect of our lives. There is hardly any device that we use in our daily life that has remained immune from the impact of semiconductors be it a child’s simple toy or a spaceship exploring the universe in quest of knowledge.
