Electronic, optical and structural properties of MnPS3: advanced spectroscopy and theoretical investigation

Abstract

In the field of van der Waals semiconductor research, studying antiferromagnetic order in materials like MnPS₃ has highlighted potential applications in heterostructures. This research examines the detailed correlations between the optical and magnetic properties of MnPS₃, providing insights into its behavior across various temperatures. Using advanced spectroscopic methods such as photoreflectance (PR) and absorption, significant optical transitions, labeled as E₁, E₂, E₃, and E_G, have been identified in bulk MnPS₃. These transitions are characterized by detailed analysis, highlighting their responses to temperature changes. Structural data from X-ray diffraction reveal how lattice parameters evolve with temperature, influencing magnetic phase transitions in MnPS₃. Understanding how optical transitions correlate with structural changes offers deeper insights into their joint influence on the optical and magnetic properties, paving the way for advances in spintronic and magneto-optical technologies. These results underscore the importance of investigating the nuanced optical and magnetic behaviors of MnPS₃ and emphasize the ongoing research needed to unlock the full potential of these layered materials for future technological innovations.
