High-performance nanosized optoelectronic devices based on van der Waals (vdW) heterostructures have significant potential for use in a variety of applications. However, the investigation nanoribbon-based vdW are still mostly unexplored. In this study, first-principles calculations, we demonstrate that Sb2S3/Sb2Se3 heterostructure, which is formed by isostructural nanoribbons stibnite (Sb2S3) and antimonselite (Sb2Se3), possesses direct band gap with typical type-II alignment, suitable...
This research extensively examines the optoelectronic and photocatalytic characteristics of α-Ge(111) monolayer for hydrogen oxygen evolution reactions. Using first-principles calculations, a direct band gap 1.48 eV 1.46 is determined under HSE06 GW approximations, respectively. widens when segmented into flakes due to quantum confinement effects. Optical analysis shows absorption peaks in visible ultraviolet ranges, with an edge ranging from 1.47 1.87 eV, dependent on inclusion excitonic...
