Binding energies of excitons in symmetric and asymmetric coupled double-quantum well structures in a magnetic field
The binding energy of excitons in the symmetric and asymmetric coupled double GaAs/$Ga_{1-x}Al_xAs$ quantum wells is calculated by using variational approach. Results have been obtained as a function of the potential ... -
Improvement in electroabsorption and the effect of the electric field in the tuneable wavelength converter
Hüseyin Sarı; Esin Kasapoğlu; Yüksel Ergün; İsmail Sökmen (1999)The numerical results of the study of a novel wavelength converter which can be tuned with the application of an external field are presented. For this device, exciton binding energies, radiuses and the absorption coefficient ... -
Parabolik Kuantum Kuyusundaki Hidrojenik Düzeyler Üzerine Manyetik Alan Etkisi
Ünal Yeşilgül; Cihat Çoban; Esin Kasapoğlu (2016)Bu çalışmada, tek parabolik kuantum kuyusunda 1s, 2s ve 2p± düzeylerindeki donor safsızlık atomunun bağlanma enerjisi, etkin kütle yaklaşımında varyasyonel olarak, kuyu genişliği ve dışarıdan uygulanan manyetik alanın bir ...
