Subdivisions of the spectra for cesaro, rhaly and weighted mean operators on c(0),c and l(P)
(SPRINGER INTERNATIONAL PUBLISHING AG, 2011)
There are many different ways to subdivide the spectrum of a bounded linear operator; some of them are motivated by applications to physics (in particular, quantum mechanics). In this study, the relationship between the ...
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 ...
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 ...
Zeeman splitting, Zeeman transitions and optical absorption of an electron confined in spherical quantum dots under the magnetic field
(2021)
In this study, we present a detailed theoretical investigation of the effect of an externally applied magnetic field on the energy states 1s, 1p, 1d and 1f in the spherical quantum dot with finite and infinite confinement ...
Influence of position dependent effective mass on impurity binding energy and absorption in quantum wells with the Konwent potential
(Elsevier, 13 July 20)
In this work, we perform a theoretical investigation on the effect of position-dependent effective mass on
binding energy and optical absorption coefficient for donor impurities in single and double quantum wells
defined ...
