High-Throughput Screening of Spin Hall Conductivity in Two-dimensional Materials

/4π, surpassing those of the known materials. Detailed analysis reveals that the significant SHC can be attributed to spin-orbit coupling (SOC)-induced gap openings at Dirac-like band crossings. Additionally, the presence of mirror symmetry can also enhance the SHC. Beyond the high SHC materials, 57 topological insulators with quantized SHCs have been identified. Our work enables rapid screening and paves the way for experimental validation, potentially accelerating the discovery of novel 2D materials optimized for spintronics applications.
