Impurity-related linear and nonlinear optical response in quantum-well wires with triangular cross section
(ELSEVIER SCIENCE BV, 2013)
The Is-like and 2p-like donor impurity energy states are studied in a semiconductor quantum wire of equilateral triangular cross section as functions of the impurity position and the geometrical size of the structure. ...
Optical coefficients in a semiconductor quantum ring: Electric field and donor impurity effects
(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 ...
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" ...
