Boron nitride and graphene 2D nanostructures from first-principles
(Bilkent University, 2010)In this thesis, the structures as well as mechanical and electronic properties of various boron nitride (BN) and graphene based two dimensional (2D) nano-structures are investigated in detail from rst-principle calculations ... -
Electro-magnetic properties and phononic energy dissipation in graphene based structures
(Bilkent University, 2008)With the synthesis of a single atomic plane of graphite, namely graphene honeycomb structure, active research has been focused on the massless Dirac fermion behavior and related artifacts of the electronic bands crossing ... -
First-principles investigation of functionalization of graphene
(Bilkent University, 2013)The graphene sheet is a single-atom thick novel material and attracts great interest due to its unique features. However, it is a metallic material with no bandgap, which makes it difficult to integrate in electronic ... -
Graphene-enabled electrically switchable radar-absorbing surfaces
(Nature Publishing Group, 2015)Radar-absorbing materials are used in stealth technologies for concealment of an object from radar detection. Resistive and/or magnetic composite materials are used to reduce the backscattered microwave signals. Inability ... -
High performance floating gate memories using graphene as charge storage medium and atomic layer deposited high-k dielectric layers as tunnel barrier
(Bilkent University, 2013)With the ongoing development in portable electronic devices, low power consumption, improved data retention rate and higher operation speed are the merits demanded by modern non-volatile memory technology. Flash ... -
Probing interfacial processes on carbon nanotubes and graphene surfaces
(Bilkent University, 2012)The surface of low-dimensional carbon (carbon nanotubes and graphene) has unique electronic properties due to the delocalized p-orbitals. Very high carrier mobility with nanoscale dimension make carbon nanotubes and ...
