Chapter 1: Glossary
Radiation from an object due to thermal energy
Model for the hydrogen atom as proposed by Niels Bohr
Radius of the electron orbit in a hydrogen atom corresponding to the lowest energy energy solution of the Bohr model
Wavelength of a particle l = h/p
The energy which an electron can have
Heat divided by absolute temperature
The average energy per particle when adding particles to a distribution but without changing the entropy or the volume. Chemists refer to this quantity as being the electro-chemical potential
Particles with half-integer spin
One of Maxwell's equations, stating that the gradient of the electric field equals the charge density, divided by the dielectric constant.
An atom consisting of a proton and an electron
Quantum mechanical concept, which states that particles can behave as waves and waves can behave as particles
Emission of electrons from a metal when applying light with photon energy larger than the workfunction of the metal
Quantum of electromagnetic radiation
Second order differential equation which relates the potential, f, to the charge density, r.
Theory which describes particles by a wavefunction
Unit of atomic energy = 13.6 eV
Atomic states which are associated with one principle quantum number
A single solution to Schrödinger's equation defined by a unique set of quantum numbers
Energy associated with the temperature of an object
A system is in thermal equilibrium if every ongoing process is exactly balanced by its inverse.
Wave description of a localized particle
Potential an electron at the Fermi energy needs to gain to escape from a solid
