QUANTUM DOT

Article : 101,261 Patent : 13,874

DEFINITIONS

Crystalline nanoparticle that exhibits size-dependent properties due to quantum confinement effects on the electronic states

Reference : ISO/TS 27687:2008

A quantum dot is a nanocrystal made of semiconductor materials that are small enough to exhibit quantum mechanical properties.

Reference : Chemistry and Physics of Semiconductor Nanocrystals

Nanoparticle or region which exhibits quantum confinement in all three spatial directions. Quantum confinement means restriction of a particle’s motion in one, two or three space dimensions when the size of a physical system is of the same order of magnitude as the particle’s de Broglie’s wavelength

Reference : ISO/TS 80004-12:2016

h-Index of nanotechnology publications

This field displays the h-index count and is based on a list of publications ranked in descending order by the Times Cited count. The h-index is the number of the item/publication in the h rank of the mentioned ranking that has at least "h" citations. For example, an h-index of 20 means 20 items have 20 citations or more. This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited.
