e/Quantum heterostructure

Information
has gloss	eng: Quantum heterostructure is a heterostructure in a substrate (usually a semiconductor material), with size restricting the movements of the charge carriers and forcing them into a quantum confinement, leading to formation of a set of discrete energy levels at which the carriers can exist. Quantum heterostructures have sharper density of states than structures of more conventional sizes.
lexicalization	eng: Quantum heterostructure
instance of	(noun) a conductor made with semiconducting material semiconductor, semiconductor unit, semiconductor device
