The effect of impurity position and doping concentration on the binding energies and total optical absorption coefficients in a δ-doped quantum well
(Springer, 08 April 2)
In this present work, for different impurity position and ionized doping concentrations,
we have theoretically investigated the linear, third-order nonlinear, and total optical

Optical properties of a triple AlGaAs/GaAs quantum well purported for quantum cascade laser active region
(3 December)
A theoretical investigation on the conduction electron states in a triple inverse parabolic AlGaAs/GaAs quantum
well, designed in the spirit of the active region for a quantum cascade laser, is performed. The study includes ...
