Multi-exciton states in flexible Rydberg aggregates
(Bilkent University, 2017-06)
Flexible Rydberg aggregates, assemblies of highly excited atoms, provide a
platform to investigate quantum phenomena like energy transport and conical
intersections. This can be achieved by doping the aggregate with an ...
Controlled lateral and perpendicular motion of atoms on metal surfaces
(Bilkent University, 1994)
Nanoscale modification of matter has been the subject of interest. Recently,
several experimental studies have demonstrated that by using a scanning
tunneling microscope one can translate atoms on metal surfaces to a ...
On the strain in silicon nanocrystals
(Bilkent University, 2009)
In this Thesis we present our achievements towards an understanding of atomistic
strain mechanisms and interface chemistry in silicon nanocrystals. The structural
control of silicon nanocrystals embedded in amorphous ...
Modeling of NC-AFM experiments by the utilization of molecular dynamics and the harmonic oscillator model
(Bilkent University, 2017-07)
Atomic force microscopy is a widely-used instrument in nanotechnology and nanoscience. Imaging of single molecules, atoms or even bond structures and tip-sample interactions with pm and pN resolution are made possible with non-contact atomic force...
First-principles investigation of graphitic nanostructures
(Bilkent University, 2013)
In this thesis, first-principles investigations of several graphene related nanosystems
based on density functional theory are presented. First, the electronic
structure of several graphene nano-ribbons both in 1D and ...
Pattern information extraction from crystal structures
(Bilkent University, 2005)
Determining crystal structure parameters of a material is a quite important issue
in crystallography. Knowing the crystal structure parameters helps to understand
physical behavior of material. For complex structures, ...
Metal coverage on single-wall carbon nanotubes : metal nanoring and nanotube formation
(Bilkent University, 2002)
The carbon nanotubes are welcomed as the basis element for electronic and
opto-electronic devices of nanometers size, the size of a few atoms. The question
of crucial importance in the physics of utilization of nanotubes ...
Robust entanglement in atomic systems
(Bilkent University, 2005)
Various models for generation of robust atomic entangled states and their
implementation with current accessible technologies are proposed and worked out.
Deterministic creation of long living Bell states with respect ...
A study of adsorption of single atoms on carbon nanotubes
(Bilkent University, 2003)
The adsorption of individual atoms on the semiconducting and metallic singlewall
carbon nanotubes (SWNT) have been investigated by using first-principles
pseudopotential plane wave method within Density Functional Theory. ...
Titanium dioxide nanostructures for photocatalytic and photovoltaic applications
