  Total-internal-reflection-based optical rotation quasi-phase-matching for efficient second-harmonic generation in Cadmium Germanium Arsenide crystal

  By Snigdha Sinha, Dr.Sumita Deb, Dr. Minakshi Deb Barma, Dr. Sumita Deb, Susmita Paul

  Abstract: This study investigates a total-internal-reflection (TIR)-based optical rotation quasi-phase-matching (ORQPM) approach for second harmonic generation within a cadmium germanium arsenide crystal slab. The crystal is coated with a thin film of yttrium oxide to facilitate precise control over phase shifts between p- and s-polarized light upon reflection at the slab-film interface. By leveraging the interplay between TIR- induced optical rotation and fractional QPM effects at designated bounce points, the configuration …

  Crystal Defects and Their Characterization in Modern Materials Science

  By T.B. Suneetha, R.M. Aadarsh Vel, R. Madhumitha Sri

  Abstract: The physical and chemical properties of crystalline solids are fundamentally dictated by deviations from structural perfection, known as crystal defects. From the point-scale vacancies that drive diffusion to the planar boundaries that determine mechanical strength, defects serve as the primary "tuning knobs" in material design. This review provides a comprehensive examination of point, line, and planar defects, exploring their formation energetics and their role in plastic deformation via crystallographic slip. …

  Solid-State Reactions: Mechanistic Insights, Kinetic Behavior and Emerging Applications in Advanced Materials

  By S. Ravichandran

  Abstract: Solid-state reactions are fundamental to the synthesis and transformation of inorganic materials, playing a crucial role in the development of ceramics, semiconductors, catalysts, and energy storage systems. Unlike reactions in liquid or gaseous phases, they are limited by restricted atomic mobility and typically require elevated temperatures to enhance diffusion and overcome activation energy barriers. These reactions proceed through interfacial contact between solid reactants, followed by nucleation of product phases and …
