This study theoretically demonstrated an insight for designing a novel tunable plasmonic biosensor, which was created by simply stacking twisted bilayer graphene (TBG) superlattice onto gold thin film. To achieve ultrasensitive biosensing, the biosensor modulated Goos-Hänchen (GH) shift. Interestingly, our proposed exhibited biosensing ability, largely depending on angle. When relative angle optimized to be 55.3°, such configuration: 44 nm Au film/1-TBG could produce ultralow reflectivity of 2.2038 × 10

Abstract 2D heterostructures have garnered significant interest in the scientific community owing to their exceptional carrier transport properties and tunable band alignment. The fabrication of these on a wafer scale is crucial for advancing industrial applications but remains particularly challenging metals with low sulfidation activity, such as Hf. Herein, one‐pot method developed fabricating wafer‐scale HfSe 2 /WSe interlayer vertically aligned van der Waals layers via interface‐enhanced selenization self‐guided growth. By depositing W layer (high activity) over Hf layer, followed by process, chemical combination between Se atoms enhanced through interfacial diffusion confined lattice reaction. Moreover, WSe grow perpendicular substrate further guide crystallization bottom layers. resulting heterostructures, characterized covalent bonds, demonstrate charge transfer, piezoelectricity, notable rectification effects, Si‐compatible transistor integration. This growth pathway may provide valuable insights into covalently connected involving well development high‐density integrated circuits.
