讲座摘要
Chromium Sulfur Bromide (CrSBr), with its van der Waals antiferromagnetic properties, presents significant potential for applications in optoelectronics, spintronics, and quantum technologies due to its sizable direct bandgap, good stability in air, and high transition temperature. This dissertation investigates the strong coupling between excitons and phonons in CrSBr, confirmed through low-temperature photoluminescence spectroscopy, and validates band splitting in both the conduction and valence bands through experimental and theoretical evidence. Additionally, a novel method for improving metal/2D contacts is proposed and experimentally verified. In conclusion, this dissertation advances our understanding of the optical, electronic, and magnetic properties of CrSBr and provides practical techniques for improving Schottky contacts in 2D materials, paving the way for future nanotechnology applications.
