Advanced tunability of optical properties of CdS/ZnSe/ZnTe/CdSe multi-shell quantum dot by the band edge engineering
Koc, Fatih; Kavruk, Ahmet Emre; Sahin, Mehmet (ELSEVIER, 2022)In this study, the advanced manipulability of wave functions in a type-II multi-shell hetero-nanostructure (MS-HNS) and the tunability of radiative exciton lifetime over a wide range with and/or without changing in transition ... -
The electronic properties of a core/shell/well/shell spherical quantum dot with and without a hydrogenic impurity
Sahin, Mehmet; Tas, Hatice (AIP Publishing1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501, 2012)In this study, we have performed a detailed investigation of the electronic properties of a core/shell/well/shell multi-layered spherical quantum dot, such as energy eigenvalues, wave functions, electron probability ... -
The inter-sublevel optical properties of a spherical quantum dot-quantum well with and without a donor impurity
Tas, Hatice; Sahin, Mehmet (AIP Publishing1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501, 2012)In this study, we have investigated the inter-sublevel optical properties of a core/shell/well/shell spherical quantum dot with the form of quantum dot-quantum well heterostructure. In order to determine the energy ... -
A model for the recombination and radiative lifetime of trions and biexcitons in spherically shaped semiconductor nanocrystals
Şahin, Mehmet; Koç, Fatih (AIP Publishing1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501, 2013)In this letter, we propose a different model to determine the recombination oscillator strength of trions and biexcitons for bound and unbound cases in the effective mass approximation. The validity of our model has been ... -
The photoionization cross section of a hydrogenic impurity in a multi-layered spherical quantum dot
Sahin, Mehmet; Tek, Firdes; Erdinc, Ahmet (AIP Publishing1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501, 2012)In this study, we have investigated the photoionization cross section of an on-center hydrogenic impurity in a multi-layered spherical quantum dot. The electronic energy levels and their wave functions have been determined ...
