semiconductor 是什么意思

音标：[ 'semikən'dʌktə ]

中文翻译与英英解释

	n. 【物理学】半导体。

	a conductor made with semiconducting material 同义词：semiconductor device, semiconductor unit,
	a substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities 同义词：semiconducting material,

A semiconductor is a material which has electrical conductivity between that of a conductor such as copper and an insulator such as glass. The conductivity of a semiconductor increases with increasing temperature, behaviour opposite to that of a metal.
