Width Dependent Electroniac and Transport Properties of Stanene Nanoribbon: Ab Initio Study

Abstract

In the context of developing effective and innovative FET-based biosensing devices, nanostructure materials perform substantially better as sensing channels. The zero band gap and unique features of graphene have sparked interest in additional graphene-structured materials for FET sensors. Stanene structure has a honeycomb lattice and out-of-plane buckling, allowing it to be employed as a sensing channel in an electronic device and allowing for charge and bandgap modulation. We have performed ab-initio calculations to find the electronic and transport properties of stanene nanoribbons of varied widths. The projected and total electronic states distribution are explored for the investigation of electronic characteristics, confirming the metallic nature of stanene nanoribbon. The current-voltage (I-V) properties of stanene nanoribbons were further investigated using the GOLLUM algorithm and equilibrium transport theory. The I–V profile is linear, indicating metallic transport properties.
