element semiconductor
1.An element introduced into a semiconductor with a negative valence greater than that of the pure semiconductor.
2.In the reference[9], a new method of using computer-generated holograms(CGH)to fabricate λ/4 phase-shifted line grating (a key element of the dynamic single-mode DFB semiconductor lasers)has been proposed, and the fabricating process has been greatly simplified.
3.This paper describes Bell Laboratories research and development of the semiconductor element and device. It relates briefly the development of the semiconductor devices in early stage,the point conduct transistor and the junction transistor,field effect transistor (FET),light emitting diodes (LED S),the Read diodes (IMPATT),and the photovoltaic cell.
5.a brittle silver-white metalloid element that is related to selenium and sulfur; it is used in alloys and as a semiconductor; occurs mainly as tellurides in ores of copper and nickel and silver and gold.
6.In the manufacture of semiconductor devices, a photographically reduced representation of a circuit or element as used to establish an etching pattern.
7.A novel high power self starting mode locked Ti∶sapphire laser with a semiconductor saturable absorber mirror (SESAM) as self starting element is demonstrated. Its sloping efficiency is 22%, average power as high as 1.7 W and pulse width shorter than 16 fs.
