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 ... -
Optical properties of the Tietz-Hua quantum well under the applied external fields
Kasapoglu, E.; Sakiroglu, S.; Ungan, F.; Yesilgul, U.; Duque, C. A.; Sokmen, I. (ELSEVIER SCIENCE BV, 2017)In this study, the effects of the electric and magnetic fields as well as structure parameter-gamma on the total absorption coefficient, including linear and third order nonlinear absorption coefficients for the optical ... -
Second and third harmonic generation associated to infrared transitions in a Morse quantum well under applied electric and magnetic fields
Restrepo, R. L.; Kasapoglu, E.; Sakiroglu, S.; Ungan, F.; Morales, A. L.; Duque, C. A. (ELSEVIER SCIENCE BV, 2017)The effects of electric and magnetic fields on the second and third harmonic generation coefficients in a Morse potential quantum well are theoretically studied. The energy levels and corresponding wave functions are ... -
Simultaneous effects of hydrostatic pressure and temperature on the nonlinear optical properties in a parabolic quantum well under the intense laser field
Ungan, F.; Yesilgul, U.; Sakiroglu, S.; Mora-Ramos, M. E.; Duque, C. A.; Kasapoglu, E.; Sari, H.; Sokmen, I. (ELSEVIER SCIENCE BV, 2013)In this present study, we have theoretically investigated the effects of hydrostatic pressure and temperature on the nonlinear optical properties in a typical GaAs/Ga0.7Al0.3As parabolic quantum well under the intense laser ... -
Study of direct and indirect exciton states in GaAs-Ga1-xAlxAs quantum dots under the effects of intense laser field and applied electric field
Mora-Ramos, M. E.; Duque, C. A.; Kasapoglu, E.; Sari, H.; Sokmen, I. (SPRINGER, 2012)The effects of intense laser radiation on the exciton states in GaAs-Ga1-xAlxAs quantum dots are studied with the inclusion of applied dc electric fields oriented along the growth direction of the system. The calculations ...
