Abstract

This study explores the electronic and structural properties of heterojunctions formed by mono-/bi-layers of graphene on a silver (Ag) (111) substrate. Using first-principles calculations, we investigate the influence of the Ag(111) substrate on graphene’s electronic structure and interfacial properties. Our findings highlight the significant modifications in the band structure, including the emergence of interface states and a bandgap opening. We also examine the charge transfer phenomena and its impact on electrical conductivity and carrier mobility. Additionally, we investigate the optical properties, such as absorption spectra and excitonic behavior, offering insights into potential optoelectronic applications. This research advances our understanding of graphene-silver heterostructures for the design and development of novel electronic and optoelectronic devices.
