Binding energy and optical absorption of donor impurity states in "12-6" tuned GaAs/GaAlAs double quantum well under the external fields
(ELSEVIER SCIENCE BV, 2019)We have investigated the binding energies of the s-symmetric ground and first excited shallow donor impurity states and the total 1s -> 2s absorption coefficient, including the first and third order corrections, in "12-6" ... -
Comparison of N-doped ZnO and N-Al codoped ZnO thin films deposited by pulsed filtered cathodic vacuum arc deposition
(INDIAN ASSOC CULTIVATION SCIENCE, 2015)N-doped ZnO and N-Al codoped ZnO films are deposited onto glass substrate at room temperature by pulsed filtered cathodic vacuum arc deposition system. The films are characterized by X-ray diffraction, Raman spectra, ... -
Effect of applied electric field on the nonlinear optical properties of modulation-doped GaAs/AlxGa1-x As double quantum well
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2019)In the present study, the effects of varying doping concentration and applied electric field on the intersubband-related optical absorption and relative refractive index change coefficients in modulation-doped GaAs/AlxGa1-x ... -
The effects of the intense laser field on the nonlinear optical properties of a cylindrical Ga1-xAlxAs/GaAs quantum dot under applied electric field
(ELSEVIER SCIENCE BV, 2015)In the present work, the effects of the intense laser field on total optical absorption coefficient (the linear and third-order nonlinear) and total refractive index change (the linear and third-order nonlinear) for ... -
Linear and nonlinear intersubband optical absorption coefficient and refractive index change in n-type delta-doped GaAs structure
(ELSEVIER SCIENCE BV, 2013)In the effective mass approximation, we have theoretically investigated the subband structure of single Si delta-doped GaAs by solving the Schrodinger and Poisson equations self-consistently. Both the linear and nonlinear ... -
Simultaneous effects of the intense laser field and the electric field on the nonlinear optical properties in GaAs/GaAlAs quantum well
(ELSEVIER SCIENCE BV, 2014)In this study, both the linear and nonlinear intersubband optical absorption coefficients and the refractive index changes are calculated as dependent on the applied electric field (F) and the laser field intensity parameter ...
