Abstract: and HfSO monolayers are indirect-gap semiconductors, and the predicted band gaps increase as we apply more advanced levels of theory. We also examine electronic properties through complex orbital hybridization. Furthermore, we observed strongly bound excitonic states in both materials, including both optically active (bright) and inactive (dark) excitons, highlighting the significant role of excitonic effects. The pronounced excitonic effects identified in both materials suggest their potential for next-generation two-dimensional (2D) optoelectronic and photonic applications.
