Summary of Currently Supported Projects

Development of a Dopped Silisium Based IR Photodecetor, Supported by Hacettepe Universitesi BAP

In this project, the primary objectives will be  i) to controllably and uniformly distribute the dopants within Si layers and forming dopped -Si atomic bonds by rabbit (in femto as well as nano second) melting procedure (annealing), and  ii) to produce single-pixel photosensing test devices. Since photosensor device performance is sensitive to surface leakage currents, the .... dopped/Si devices will be thoroughly characterised to keep the surface leakage currents to a minimum which should ultimately yield novel IR devices with a high signal-to-noise ratio.

The Act of Nonlinearity Enhancement of Fano Resonances on the Quantum Entanglement Features of Plasmonic Nanoparticles, Supported by TUBITAK 1001

Plasmonic oscillations, emerging on nanoparticles, can localize the incident optical radiation at nanometer dimensions. Such localizations bring the nonlinear optical properties to light. Recently, our research group has both demonstrated both theoretically and experimentally that Fano resonances can further enhance the nonlinear conversion processes (e.g. second harmonic generation) about a 1000 times on top of the localization effects. In this project, we investigate the quantum entanglement features of such nonlinearity-enhanced systems

OSL Based Small Field Dosimetry of Cyberknife SRS/SBRT Sysytem, Supported by TUBITAK 1001

Stereotactic radiosurgery (SRS) and radiotherapy (SRT) systems, e.g. Cyberknife, have made the radiotherapy applications with the small beam size under 3x3 cm2 possible. However, uncertainties arise in clinical dosimetry of small fields because of the difficulties and even impossibilities in meeting the requirements of beam size and reference dosimetric setup used in traditional protocols of absorbed dose applications. The requirement of dosimetric measurement using water phantom with the purpose of cross calibration will be apparent in the situation of increasing uncertainty in detector measurements. Our planned study includes (i) determination of delivered dose of small field irradiation using passive dosimeters accordance with the recommendations of International Atomic Energy Agency (IAEA) and (ii) the determination of error correction factors by evaluation of dosimetric measurement data acquired with active/passive dosimetric methods with Monte Carlo simulations
