Department of Electrical and Electronic Engineering Graphene nanoribbon NDR NEGF Quantum well Resonant tunneling 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.2015.7388632 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 equation was coupled with Poisson's equation to obtain the desired device characteristics. This device shows promising results including the NDR effect at very low bias, at 0.12V, with peak current of 1.78μA and peak to valley current ratio (PVCR) of ∼20. We further show that the device performance has strong dependence on back gate voltage. 2016-11-23T09:32:52Z 2016-11-23T09:32:52Z 2015 Conference Paper Saha, G., Saha, A. K., & Harun-Ur Rashid, A. B.
