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 SCIENTIFIC PUBL CO PTE LTD5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE, 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 ... -
A detailed investigation of the electronic properties of a multi-layer spherical quantum dot with a parabolic confinement
Akgul, Selcuk; Koksal, Koray; Sahin, Mehmet (ELSEVIER, 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 & FRANCIS LTD2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 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, ... -
The effect of dilute nitrogen on nonlinear optical properties of the InGaAsN/GaAs single quantum wells
Sahin, Mehmet; Koksal, Koray (SPRINGER, 2012)In this study, we investigate the linear and third order nonlinear optical properties of InGaAsN/GaAs depending on nitrogen content and laser dressing parameter. As theoretical models, band anticrossing and model solid ... -
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 & FRANCIS LTD2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 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 Publishing 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 ...
