The electronic, thermodynamic, and optical properties of a new type two-dimensional Janus layer (JL) consisting exclusively chalcogens are investigated using first-principles calculations. permutations on atomic sites provide increased stability due to the multi-valency chalcogens, heavier central atom further stabilizes coordination number. JLs indirect bandgap materials with larger than 1.23 eV, making them suitable for photocatalytic activity. Different feasible chemical potentials analyzed, chalcogens' poor limits proposed fabricate JLs. Based comparison formation energy, energetic profile is identified as EfTeSeS < E fSSeTe EfSeSTe, irrespective chalcogen. Hence, TeSeS more stable JL arrangements SSeTe SeSTe. flat bands around Fermi energy level reduction in path length between maximum conduction minimum valence explain magnitude multiple peaks observed spectra These absorptions turn studied into potential candidates water splitting. optimized reveals that band edges efficiently straddle redox at different pH levels.
