Pd-PEPPSI: X-ray Structure, Spectroscopic Analyses, and Quantum Mechanical Studies
(2021)
Pyridine enhanced precatalyst preparation stabilization and initiation (PEPPSI) complexes contain
two halides, an unstable pyridine derivative and a bulky N-heterocyclic carbene (NHC) ligand. In this
study, a new ...
Theoretical computation of normalised radii, density and global hardness as a function of orbital exponent
(Springer International Publishing, 21 Februar)
The recent work has an aim to establish a pivotal role of orbital exponent in the
normalized atomic radii, atomic density and atomic hardness. These three periodic
descriptors help to understand the real scenario of an ...
Equilibrium, thermodynamic, and kinetic modeling studies for the adsorptive removal of oxyanions from water
(TAYLOR & FRANCIS INC, DEC 2021)
Water is being contaminated by different oxyanions which have many negative effects on the human body. This study deals with the adsorptive removal of Cr2O7-2, AsO4-3, and ClO4-1 oxyanions from water using diethanolamino ...
Shallow‑donor impurity effects on the far infrared electron–electron optical absorption coefficient in single and core/shell spherical quantum dots with Konwent‑like confinement potential
(2022)
In this study, the electronic and optical properties of single or core/shell quantum dots,
which are formed depending on the parameters in the selected Konwent potential, are
investigated. Namely, the effects of the size ...
Effect of position-dependent effective mass on donor impurity- and exciton-related electronic and optical properties of 2D Gaussian quantum dots
(2022)
Using the compact density matrix scheme and the effective mass approximation, we study the influence of positiondependent
electron and heavy-hole mass distributions on the impurity-related electronic properties, excitonic ...
Optical Properties of Cylindrical Quantum Dots with Hyperbolic-Type Axial Potential under Applied Electric Field
(2022)
In this paper, we have researched the electronic and optical properties of cylindrical
quantum dot structures by selecting four different hyperbolic-type potentials in the axial direction
under an axially-applied electric ...
Theoretical Study of the Exciton Binding Energy and Exciton Absorption in Different Hyperbolic-Type QuantumWells under Applied Electric, Magnetic, and Intense Laser Fields
(2022)
In this study, we investigated the exciton binding energy and interband transition between
the electron and heavy-hole for the single and double quantum wells which have different hyperbolictype
potential functions subject ...
Photoionization cross section of a D+ 2 complex in quantum dots: the role of donor atoms configuration
(2022)
This study reports a theoretical investigation on the electronic spectrum and the photoionization cross section of a singly
ionized double donor complex D+
2 confined in a two-dimensional quantum dot with Gaussian ...
Influence of external fields on the exciton binding energy and interband absorption in a double inverse parabolic quantum well
(2022)
Ground-state binding energy and optical absorption coefficient of exciton in a symmetric double inverse
parabolic quantum well system in the presence of external electric and magnetic fields are investigated
theoretically. ...
Energy spectrum and interlevel transitions within the conduction band of a D+ 2 complex confined in a spherical quantum dot
(2022)
In this work, we have performed a theoretically study on the energy spectrum, binding
energy and interlevel transitions within the conduction band of a D+
2 complex confined in
a spherical quantum dot with finite ...
