Donor Impurity-Related Optical Absorption in GaAs Elliptic-Shaped Quantum Dots
Londono, M. A.; Restrepo, R. L.; Ojeda, J. H.; Huynh Vinh Phuc; Mora-Ramos, M. E.; Kasapoglu, E.; Morales, A. L.; Duque, C. A. (HINDAWI LTD, 2017)The conduction band and electron-donor impurity states in elliptic-shaped GaAs quantum dots under the effect of an externally applied electric field are calculated within the effective mass and adiabatic approximations ... -
Optical coefficients in a semiconductor quantum ring: Electric field and donor impurity effects
Duque, C. M.; Acosta, Ruben E.; Morales, A. L.; Mora-Ramos, M. E.; Restrepo, R. L.; Ojeda, J. H.; Kasapoglu, E.; Duque, C. A. (ELSEVIER SCIENCE BV, 2016)The electron states in a two-dimensional quantum dot ring are calculated in the presence of a donor impurity atom under the effective mass and parabolic band approximations. The effect of an externally applied electric ...
