Scanning hall probe microscopy (SHPM) using quartz crystal AFM feedback
(Bilkent University, 2005)Scanning Hall Probe Microscopy (SHPM) is a quantitative and non-invasive technique for imaging localized surface magnetic field fluctuations such as ferromagnetic domains with high spatial and magnetic field resolution ... -
Selective plasmonic control of excitons and their non-radiative energy transfer in colloidal semiconductor quantum dot solids
(Bilkent University, 2009)To date extensive research has proved that semiconductors and metals exhibit extraordinary optical properties in nano-dimensions compared to their bulk counterparts. For example, an interesting effect is observed in ... -
Silicon and carbon based nanowires
(Bilkent University, 2004)Nanowires have been an active field of study since last decade. The reduced dimensionality end size allowing electrons can propagate only in one direction has led to quantization which are rather different from the bulk ... -
Silicon nanocrystal doped polymer nanowire arrays

Silicon oxynitride layers for applications in optical waveguides
(Bilkent University, 2000) -
Silicon-on-insulator optical waveguides and waveguide devices
(Bilkent University, 2000)Silicon-on-insulator(SOI) optical waveguides, directional couplers and some types of MMI couplers were designed, fabricated and characterized at a wavelength of 1.55 /im. Effective index method and the single mode ... -
Slow light in Germanium nanocrystals
(Bilkent University, 2009)The phenomena of quantum coherence has been applied with great success in the atomic systems. For optoelectronic applications the interest is inherently directed towards the semiconductor heterostructures. Large number ... -
Sonic Hawking Radiation from a blackhole laser
(Bilkent University, 2018-06)The quantum thermal radiation from a black hole (BH) known as “Hawking Radiation” or “Black Hole Evaporation” results from studying quantum fields in the curved space-time of the horizon of a BH. Experimentally, the ... -
Sorting of chiral microswmmers
(Bilkent University, 2014)Microscopic swimmers, for example chemotactic bacteria and cells, are capable of directed motion by exerting a force on their environment. In some cases, including bacteria and spermatozoa swimming near boundaries, or ... -
Spatial and temporal symmetry breaking in nonlinear laser lithography
(Bilkent University, 2023-01)Symmetry breaking is ubiquitous in nonlinear systems. This is also the case for Nonlinear Laser Lithography (NLL), in which an ultrafast laser beam incident on a material surface causes the infinite fold rotational symmetry ... -
Spatial properties of quantum multipole radiation
(Bilkent University, 2000)Complete quantum mechanical treatment of multipole radiation is constructed. Vacuum noise of polarization for transversally and longitudirudly polcirized fields is discussed for different total angular momentum values ... -
Stability of two dimensional (2D) structures based on GaAs
(Bilkent University, 2015-08)Graphene is a two dimensional material isolated for the first time in 2004. After this, two dimensional materials has become an appealing research area for the scientists because of their exotic properties. In search ... -
Strained empirical pseudopotential generation from hybrid density functionals: GaAs, InAs,GaSb, InSb
(Bilkent University, 2015-08)Self-assembled quantum dots composed of III-V compounds receive considerable attention due to their potential applications on spintronics and quantum informa- tion processing. Here, lattice mismatch between two materials ... -
Strongly interacting one-dimensional Bose condensates
(Bilkent University, 2000)Recent observation of Bose-Einstein condensation in dilute alkali gzises led to a great interest in this area both experimentally and theoretically. The most important characteristics of a Bose-Einstein condensate is ... -
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. ... -
Study of anisotropic particles in active bath
(Bilkent University, 2015)Brownian (passive) particles undergo random motion due to thermal agitation in the surrounding medium. In recent years, a lot of attention has been devoted to study active Brownian particles, i.e., microscopic particles ... -
A study of the modern theory of polarization on extensions of one dimensional topological insulators and disordered systems
(Bilkent University, 2021-12)We work on identifying topological and quantum phase transition via the modern theory of polarization. We go through the problem of electrostatics definition of absolute polarization via a discrete chain of anions and ... -
Sub-wavelength resolution in a photonic crystal superlens
(Bilkent University, 2003)Materials that can bend light in the opposite direction to normal (’left-handed’ materials) reverse the way in which refraction usually works-this negative refractive index is due to simultaneously negative permeability ... -
Subwavelength surface plasmon interferometer for high-throughput sensing
(Bilkent University, 2012)Small detection volume, increased analysis speed and reduced cost are the main driving forces for miniaturized lab-on-a-chip systems. Subwavelength holes on opaque metal films provide a unique configuration for miniaturized ... -
