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 ... -
Optical Properties in a ZnS/CdS/ZnS Core/Shell/Shell Spherical Quantum Dot: Electric and Magnetic Field and Donor Impurity Effects
Sahin, Mehmet; Toscano-Negrette, Rafael G.; Leon-Gonzalez, Jose C.; Vinasco, Juan A.; Morales, A. L.; Koc, Fatih; Kavruk, Ahmet Emre; Mora-Ramos, M. E; Sierra-Ortega, Jose; Martinez-Orozco, J. C.; Restrepo, R. L; Duque, C. A. (MDPI, 2023)A theoretical analysis of optical properties in a ZnS/CdS/ZnS core/shell/shell spherical quantum dot was carried out within the effective mass approximation. The corresponding Schrödinger equation was solved using the ... -
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 ...
