dopant 是什么意思

中文翻译与英英解释

	n. 【物理学】掺杂剂，掺杂物。

A dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) in order to alter the electrical properties or the optical properties of the substance. In the case of crystalline substances, the atoms of the dopant very commonly take the place of elements that were in the crystal lattice of the material.
