Modeling Interactions of Graphene with Electrolyte in the Field-Effect Transistor Configuration
(University of Waterloo, 2015-08-14)
Understanding interactions of graphene with an electrolyte is fundamental to its applications for chemical and biological sensors, where graphene operates in the configuration of a field-effect transistor with its surface ...
Effects of the Dielectric Environment on the Electrical Properties of Graphene
(University of Waterloo, 2013-08-30)
This thesis provides the study of graphene’s electrostatic interaction with the substrate surrounding it. Mathematical models based on current experimental configurations of graphene field-effect transistors (FET) are ...
Analysis of Plasmons Sustained on the Surface of Graphene
(University of Waterloo, 2014-08-11)
This thesis is broken into two parts, both dealing with the role of two-dimensional graphene in electronic and optical applications. The first section develops a phenomenological relationship for the polarizability of the ...
Nonlinear screening of external charge by doped graphene
(University of Waterloo, 2010-04-28)
In the rst part of this thesis we discuss some details of properties of graphene and we explain the tight-binding approach to nd the energy spectrum in graphene. In the second part of the thesis, we solve a nonlinear ...
