M Harun Ur Department of Electrical and Electronic Engineering GNR Interband Intersubband Photodetector Quantum well-in-well This conference paper was presented in the 15th IEEE International Conference on Nanotechnology, IEEE-NANO 2015; Rome; Italy; 27 July 2015 through 30 July 2015 [© 2015 Institute of Electrical and Electronics Engineers Inc.] The conference paper's definite version is available at: http://10.1109/NANO.2015.7389010 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 the self-consistent simulation between Non-equilibrium Green's function method and electrostatic Hartree potential distribution. The proposed device structure can incorporate both of the interband and intersubband transitions depending on a back gate voltage. The optical absorption frequency can be varied through the back gate voltage. The confined energy states and quantum efficiency of the device have been determined along with the dark current dependence on the bias voltages. 2016-11-24T08:56:21Z 2016-11-24T08:56:21Z 2015 Conference Paper Saha, A.
