Crystal structural investigation of 2D materials

Abstract

Understanding the crystal structure of two-dimensional (2D) materials is crucial for determining their physical properties and potential applications. This thesis focuses on the structural investigation of Two dimensional Materials like ZrSe2, TiSe2, and ZrSe3, synthesized using the Chemical Vapor Transport (CVT) method. The study employs X-ray Diffraction (XRD) to determine phase purity, lattice parameters, and symmetry, providing insights into stacking configurations and possible distortions. Raman Spectroscopy is used to analyze vibrational modes, which are directly influenced by structural arrangements and layer interactions. Additionally, Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray Spectroscopy (EDX) help examine surface morphology and elemental composition, ensuring proper stoichiometry. The results offer a deeper understanding of how structural variations affect the stability and properties of these materials, contributing to the broader exploration of transition metal chalcogenides for optoelectronic and energy-related applications.
