electron wave function
31Gas electron diffraction — (GED) is one of the applications of electron diffraction techniques. The target of this method is the determination of the structure of gaseous molecules i.e. the geometrical arrangement of the atoms from which a molecule is built up.The… …
32Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… …
33Scanning tunneling microscope — Image of reconstruction on a clean Gold(100) surface …
34Density functional theory — Electronic structure methods Tight binding Nearly free electron model Hartree–Fock method Modern valence bond Generalized valence bond Møller–Plesset perturbation theory …
35Spin (physics) — This article is about spin in quantum mechanics. For rotation in classical mechanics, see angular momentum. In quantum mechanics and particle physics, spin is a fundamental characteristic property of elementary particles, composite particles… …
36Electronic density — In quantum mechanics, and in particular quantum chemistry, the electronic density is a probabilistic measure of the number of electrons occupying a given element of space. It is a scalar quantity depending upon three spatial variables and is… …
37Hartree-Fock — In computational physics and computational chemistry, the Hartree Fock (HF) method is an approximate method for the determination of the ground state wavefunction and ground state energy of a quantum many body system.The Hartree Fock method… …
38Quantum cascade laser — Quantum cascade lasers (QCLs) are semiconductor lasers that emit in the mid to far infrared portion of the electromagnetic spectrum and were first demonstrated by Jerome Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson,… …
39Orbital hybridisation — Four sp3 orbitals. Three sp2 orbitals. In …
40Ballistic conduction — is the characteristic of a material, known as a ballistic conductor , which has crystalline properties that allow electrons to flow through the material without collisions. The material must be free of impurities that electrons could collide with …
