Influence of Ni thin flim structural properties over graphene growth by CVD
(Izmir Institute of Technology, 2013)
This thesis work focused on the effect of polycrystalline Nickel (Ni) TM thin film structure on the growth graphene by chemical vapor deposition (CVD). TM films were deposited by magnetron sputtering technique on Si/SiO2 ...
The growth of epitaxial graphene for two-dimensional electronics
(Izmir Institute of Technology, 2015-07)
Graphene is a fundamentally new type of 2D electronic material exhibits extraordinary properties. In this work, we used the thermal decomposition of SiC in vacuum principle to grow epitaxial graphene on Both C-face and ...
Developing epitaxial graphene electrodes for silicon carbide based optoelectronic devices

In this thesis work, I studied the fabrication and characterization of graphene-semiconductor-graphene ultraviolet photodetector based on the rectifying character of Schottky junction at the interface between epitaxial ...
Modelling electronic and structural properties of graphene and transition metal chacogenide nanostructures
(Izmir Institute of Technology., 2016-07)
The purpose of this thesis is to investigate the electronic and structural properties of one- and two-dimensional materials such as graphene, graphene-like transition metal chalcogenides by using density functional theory. ...
Calculations of electric and magnetic properties of triangular graphene fragments using density functional theory: Effects of edge functionalization and electric field
(Izmir Institute of Technology, 2013)
The triangular graphene flakes (N-TGFs) we consider have equilateral triangular shapes with zigzag edges, where N denotes the number of edge hexagonal cells in one side of the triangle. Termination of these N-TGF structures ...
Electronic, magnetic and optical properties of graphene nanoribbons
(Izmir Institute of Technology, 2016-06)
