A detailed investigation of the electronic properties of a multi-layer spherical quantum dot with a parabolic confinement
Akgul, Selcuk; Sahin, Mehmet; Koksal, Koray (Elsevıer Scıence Bv, 2012)In this work, we aim a detailed investigation of the electronic properties of a spherical multi-layer quantum dot with and without a hydrogenic impurity. The structure is introduced in the form of core/shell/well/shell ... -
Effect of a buffer layer between the shell and ligand on the optical properties of an exciton and biexciton in type-II quantum dot nanocrystals
Koc, Fatih; Koksal, Koray; Sahin, Mehmet (Taylor & Francıs Ltd, 2017)In this study, we have investigated the effect of the buffer layers on the electronic and optical properties of an exciton (X) and a biexciton (XX) in a type-II CdTe/CdSe quantum dot nanocrystal. In an experimental study, ... -
ESTIMATING SOLAR RADIATION BY MACHINE LEARNING METHODS
Ertugrul, Edip; Sahin, Mehmet; Aggun, Fikri (Ieee, 2015)Solar energy, which is clean and renewable energy source, is a popular subject. The estimation of solar radiation can be done instead of long term measurements. Therefore, the satellite and meteorological values of 53 ... -
The angular electronic band structure and free particle model of aromatic molecules: High-frequency photon-induced ring current
Oncan, Mehmet; Koc, Fatih; Sahin, Mehmet; Koksal, Koray (World Scıentıfıc Publ Co Pte Ltd, 2017)This work introduces an analysis of the relationship of first-principles calculations based on DFT method with the results of free particle model for ring-shaped aromatic molecules. However, the main aim of the study is ... -
The electronic and optical properties of a triexciton in CdSe/ZnS core/shell quantum dot nanocrystals
Akturk, Abdurrahman; Tas, Hatice; Koksal, Koray; Sahin, Mehmet (Taylor & Francıs Ltd, 2016)In the study, we aim to investigate the electronic and optical properties of single excitons, biexcions and triexcitons in a CdSe/ZnS core/shell quantum dot nanocrystal. The electronic structure has been determined by ... -
The linear optical properties of a multi-shell spherical quantum dot of a parabolic confinement for cases with and without a hydrogenic impurity
Sahin, Mehmet; Koksal, Koray (Iop Publıshıng Ltd, 2012)Throughout this work, we aim to explore the linear optical properties of a semiconductor multi-shell spherical quantum dot with and without a hydrogenic donor impurity. The core and well layers are defined by the parabolic ...
