how to simulate insulator in a GNRFET with matlab?
Closed | Responses: 0
I want to apply gate voltage on a graphene nanoribbon as a channel in a GNRFET. then I want to solve poisson equation but I need to know the voltage on channel as the boundary...

Graphene Nanoribbon Hall Effect
Closed | Responses: 2
I'm new here in the community, and I am currently working on the Hall effect of GNRs.
My question is that, compared to the Hall effect in Graphene, how do I account...
How i can solve poisson equation in decoupled mode space NEGF?
I want solve poisson equation in decoupled mode space Negf for graphene nanoribbons ,but...
SPICE Model of Graphene Nanoribbon FETs (GNRFET)
12 Jul 2013 | Contributor(s):: Ying-Yu Chen, Morteza Gholipour, Artem Rogachev, Amit Sangai, Deming Chen
This is a SPICE compatible model for both MOS- and Schottky-Barrier-type Graphene Nano-Ribbons Field-Effect Transistor. These MOS-GNRFET and SB-GNRFET models are implemented in HSPICE and can be used for circuit simulations. The model is implemented based on the...

How to choose the range of convergence for self-consistent solutions for gnrfet?
Closed | Responses: 1
Hi, i’m trying to choose the range of convergence for self-consistent solution of potential(from poisson’s equation) and density ( from NEGF) for graphene nanoribbon field effect...
graphene sheet resistivity
Open | Responses: 1
R=Rs W/L ,where Rs is the sheet resistivity. and it is a constant
Now for graphene, as W decreases, R should also decrease(because Rs is constant).But R increases ,they say no. of conducting...
Ripples and Warping of Graphene: A Theoretical Study
08 Jun 2010 | | Contributor(s):: Umesh V. Waghmare
We use first-principles density functional theory based analysis to understand formation of ripples in graphene and related 2-D materials. For an infinite graphene, we show that ripples are linked with a low energy branch of phonons that exhibits quadratic dispersion at long wave-lengths. Many...
