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 ...
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 ...
Double quantum well resonant tunneling negative differential resistance device design using graphene nanoribbons
(© 2015 Institute of Electrical and Electronics Engineers Inc., 2015)
In this paper double quantum well resonant tunneling negative differential resistance (NDR) device based on intrinsic armchair graphene nanoribbon (A-GNR) is proposed. Non-equilibrium Green's function (NEGF) based transport ...
