Non Radiative Electronic Transitions in Ionic Crystals I* Crystal model and calculation of states
نویسنده
چکیده
The theory of non radiative electronic transitions is represented in two papers. In the first of these we calculate wavefunctions, energies, matrix-elements etc. In the second we discuss the general reaction mechanism and apply the theory to two examples. The wavefunction of a crystal volume containing one defect is calculated on the base of a microscopic theory. For our numerical discussion we used as an example an anion vacancy in MgO, LiF, NaCI, NaBr, KC1, KBr, KJ. The results are collected in Table 1 and 2. As far as experimental data have been available they agree completely with our results.

Non Radiative Electronic Transitions in Ionic Crystals II* Reaction Formalism and Results
A general formalism to describe radiationless electronic decay (RED) is developed. Two con ditions are derived th a t m ust be fulfilled to make R ED possible. Using the data derived in part I of this paper the general formulae are applied to a F-center in KC1 and MgO. In KC1 the con ditions for RED are not fulfilled while in MgO R ED proves to be more probable than radiative decay. This is i...
متن کاملInvestigation on optical properties in the surface of KClxBr1-x mixed crystals irradiated to gamma radiation (A new approach)
Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...
متن کاملDensity Functional Studies on Crystal Structure and electronic properties of Potassium Alanate as a candidate for Hydrogen storage
Potassium Alanate is one of the goal candidates for hydrogen storage during past decades. In this report, initially the Density Functional Theory was applied to simulate the electronic and structural characteristic of the experimentally known KAlH4 complex hydride. The relaxation of unit cell parameters and atomic positions was performed until the total residual force reduced less than 0.001ev ...
متن کاملRadiative topological states in one-dimensional resonant photonic crystals
We present a theory of topological edge states in onedimensional resonant photonic crystals with compound unit cell. We demonstrate how the structure, despite being onedimensional, can be characterized by topological indices. Contrary to conventional electronic topological states the modes under consideration are radiative, i.e., they decay in time due to the light escape through the structure ...
متن کاملComputing equations of state for ionic solids
Two diierent theoretical approaches to the total energy of solids have been applied to describe the equations of state (EOS) of ionic halides and oxides. The rst one is the ab initio Perturbed Ion (aiPI) model, a quantum-mechanical technique that solves the Hartree-Fock equations of a crystal in a localized Fock space. The second one is an interatomic force model implemented in a new computatio...
