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 ... -
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 ...
