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
absorption coefficients corresponding to ...
Combined effects of electric, magnetic, and intense terahertz laser fields on the nonlinear optical properties in GaAs/GaAlAs quantum well with exponentially confinement potential
(23 Novembe)
We are presenting a theoretical investigation on the effects of applied electric,
magnetic, and non-resonant intense laser field on the coefficients of intersubband linear,
third-order nonlinear, and total optical ...
Effects of intense laser field and position dependent effective mass in Razavy quantum wells and quantum dots
(2021)
Using the effective mass and parabolic band approximations, we investigated the position-dependent effective mass and non-resonant intense laser field effects on the first and third-order corrections of the absorption and ...
The anisotropy effects on the shallow-donor impurity states and optical transitions in quantum dots
(12 August )
In this work, we theoretically investigate the anisotropy effects on impurity states
and optical transitions in quantum dots. In particular, we investigate the role of the impurity
position on the binding energy and ...
Magneto-optical properties of impurity associated photoionization cross-section in laser-driven delta-doped quantum wires
(27 July 20)
Within the structure of parabolic band and effective-mass approximations, the effects of magnetic and intense
terahertz laser fields on the donor impurity-associated photoionization cross-section and nonlinear optical
properties ...
A Joining Dissimilar Material Pairs by Mechanical Locking Method (MLM)
(International Journal of Precision Engineering and Manufacturing, 2021)
Several methods that have been used in joining material pairs with diferent properties share many disadvantages. To overcome these disadvantages, the current study introduces mechanical locking method (MLM), which is a new ...
Numerical simulation of linear and nonlinear optical properties in heterostructure based on triple Gaussian quantum wells: effects of applied external fields and structural parameters
(31 August )
In this work, we present a theoretical simulation of the impact of applied external
fields and structural parameters on the total (linear plus nonlinear) optical absorption
coefficient (TOAC) and total refractive relative ...
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 ...
Shallow Donor Impurity States with Excitonic Contribution in GaAs/AlGaAs and CdTe/CdSe Truncated Conical Quantum Dots under Applied Magnetic Field
(MDPI, 25 October)
Using the effective mass approximation in a parabolic two-band model, we studied the effects of the geometrical parameters, on the electron and hole states, in two truncated conical quantum dots: (i) GaAs-(Ga,Al)As in the ...
Position dependent effective mass effect on the quantum wells with three-parameter modified Manning potential
(17 June 20)
This article reports a theoretical study of the intersubband optical properties in quantum wells
with modified Manning potential considering the effects of position-dependent effective mass.
Calculations are made in the ...
