Transition in electronic transport properties of graphene nanoribbon due to the adsorption of atoms and molecules
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2015)The adsorption effects of gas molecules on semiconducting armchair graphene nanoribbon (A-GNR) are studied considering on the significant changes over current-voltage characteristics, device density of states and electrostatic ... -
Vapor adsorption limitation of graphene nanoribbons in quasi conductance increment: a NEGF approach
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2015)The adsorption of H2O molecules on Armchair Graphene Nanoribbons (A-GNR) was theoretically studied using Non Equilibrium Green Function (NEGF) formalism to determine Device Density of States (DDOS), Electrostatic Effective ... -
Numerical study on graphene nanoribbon quantum well-in-well interband and intersubband photodetector
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2015)The optical properties of well in well structure formed by armchair graphene nanoribbons (A-GNRs) are studied. A-GNR sheet is modeled by 3rd nearest tight-binding parameter. The optical properties are studied by employing ... -
