THEORETICAL STUDY OF UNIAXIAL STRESS, SPATIAL DIELECTRIC FUNCTIONS AND TEMPERATURE DEPENDENCE OF PHOTOIONIZATION CROSS-SECTION OF DONOR IMPURITIES IN A GaAs QUANTUM WELL DOT
(Pwani University, 2019-09-29)
he present work considers photoionization cross-section of donor impurities in a GaAs quantum well dot of cylindrical geometry. The quantum dot is itself embedded in a Ga Al As 1x x matrix. A trial wave function that ...
