Impurity Photoionization Cross-Section and Intersubband Optical Absorption Coefficient in Multilayer Spherical Quantum Dots
(Vasyl Stefanyk Precarpathian National University, 2021-10-05)
Energy spectrum, wave functions and binding energies of the electron to the donor impurity ion located in the center of a multilayer spherical quantum dot (MSQD) consisting of a core (GaAs) and two spherical shells ...
Core-shell type-II spherical quantum dot under externally applied electric field
This study presents a simple one-band model within the effective mass approximation to describe the electric field impact on the energy structure and interband electron quantum transitions in type-II CdSe/ZnTe and ZnTe/ ...
Optical absorption, photoionization and binding energy of shallow donor impurity in spherical multilayered quantum dot
Energy spectrum, wave functions and binding energies of the electron to the donor impurity ion located in the center of a multilayer spherical quantum dot (MSQD) consisting of a core (GaAs) and two spherical shells (AlxGa1–xAs ...
Optical absorption in core-shell quantum antidot under applied co-directed electric and magnetic fields.
(Taylor & Francis Group, 2022-05-13)
Using the matrix diagonalization method within the effective mass approximation and the rectangular potential profile, we investigate optical absorption coefficients (OAC) in the core-shell quantum anti- dot (QAD) ...
Optical absorption in core-shell quantum antidot with donor impurity under applied magnetic field
The influence of the magnetic field and off- central donor impurity on the energy spectrum and wave functions of an electron in the inverted core-shell QD are calculated. On this basis, the dependence of the binding energy ...
Magnetic spring on the base ring magnet
(Волинський національний університет імені Лесі Українки, 2022-08-05)
The purpose of this work is to calculate the magnetic field induction distribution of a ring magnet and to investigate the force of its interaction with a cylindrical magnet for the possibility of using them as a magnetic ...
Rainbows of Different Order in Water Droplets and Glass Beads
A single reflection of sunlight inside a falling raindrop produces the primary rainbow. Double reflection gives rise to the secondary rainbow. This Demonstration calculates the parameters for rainbows of the first six ...
Rainbows of Multiple Orders
This Demonstration shows the position and colors for the first 10 orders of rainbows formed by the reflection and refraction of the Sun's rays in drops of water.
