endothermic reaction
Materials science; Material physics
That requires energy in order for the reaction to occur. In particle physics, the total incident particle masses are less than the final particle masses for an endothermic ...
tunnel effect
Materials science; Material physics
The ability of a particle to pass through a region of finite extent in which the particle's potential energy is greater than its total energy; this is a quantum-mechanical ...
tunneling
Materials science; Material physics
The ability of a quantum particle to penetrate a barrier even if its energy is less than the energy height of the barrier. Tunneling comes about because the wave function of a ...
phosphorescence
Materials science; Material physics
The absorption of energy followed by an emission of electromagnetic radiation. Phosphorescence is a type of luminescence and is distinguished from fluorescence by the property ...
Gaussian line shape
Materials science; Material physics
The absorption spectrum of light with a Gaussian line shape is seen in inhomogeneous broadening. One of the mechanisms resulting in Gaussian line shape is Doppler broadening. See ...
optical pumping
Materials science; Material physics
The action of an external light beam when it raises atoms from the ground state to an excited state by photon absorption. Laser action follows from the population inversion that ...
feedback
Materials science; Material physics
The action of returning the output of a device such as an amplifier to its input. There are two types of feedback: positive feedback and negative feedback. If the relative phases ...
