Magneto-Exciton Energy in Cylindrical Indium Arsenide Quantum Dots Affected by External Parameters

(Marwan Zuhair Elias)

Abstract

The effects of temperature, pressure, and an applied magnetic field on the energies of a cylindrical layer of indium arsenide (InAs) quantum dots, with and without Coulomb interaction, are investigated. Exciton energy depends significantly on these parameters. The results show that the ground-state and excited-state energies increase with rising temperature and applied magnetic field (blue shift), but that both energy states decrease with increasing pressure (red shift). As the temperature increases for higher states, the sensitivity of magneto-exciton energy also increases. The outcomes obtained for layered and ring-shaped systems exhibit a universal quality, making them particularly interesting.
