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 ...

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/ ...

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 ...

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) ...

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 ...

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 ...

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 ...

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.
