112Perturbation theory (quantum mechanics) — In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a …
113Tunnel magnetoresistance — Magnetic tunnel junction (schematic) The Tunnel magnetoresistance (TMR) is a magnetoresistive effect that occurs in magnetic tunnel junctions (MTJs). This is a component consisting of two ferromagnets separated by a thin insulator. If the… …
114Cryogenic particle detectors — operate at very low temperature, typically only a few degrees above absolute zero. These sensors interact with an energetic elementary particle (such as a photon) and deliver a signal which can be related to the type of particle and the nature of …
115Nanomesh — Perspective view of nanomesh, whose structure ends at the back of the figure. The distance between two pore centers is 3.2nm, and the pores are 0.05nm deep. The nanomesh is a new inorganic nanostructured two dimensional material, similar to… …
116DNA nanotechnology — seeks to make artificial, designed nanostructures out of nucleic acids, such as this DNA tetrahedron.[1] Each edge of the tetrahedron is a 20 base pair DNA double helix, and each vertex is a three arm junction. DNA n …
117nuclear fission — fission (def. 2). [1885 90] * * * Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles. The energy released in the… …
118Mass — This article is about the scientific concept. For the substance of which all physical objects consist, see Matter. For other uses, see Mass (disambiguation). Classical mechanics …
119High-temperature superconductivity — Unsolved problems in physics What causes superconductivity at temperatures above 50 kelvin? High temperature superconductors (abbreviated high Tc or HTS) are materials that have a superconducting transition temperature (Tc) above 30 K… …
120Stranski-Krastanov growth — (SK growth, also Stransky Krastanov or Stranski Krastanow) is one of the three primary modes by which thin films grow epitaxially at a crystal surface or interface. Also known as layer plus island growth , the SK mode follows a two step process:… …
