0 a substance, such as silicon, that conducts electricity more easily than an insulator but less easily than a conductor, and is used in electronic circuits -- chất bán dẫn
Semiconductors are used extensively in solid-state electronic devices and computers.
In addition to silicon, other common semiconductors used in the industry are germanium and gallium arsenide.
Prior to the introduction of semiconductors, electronic circuits used vacuum tubes to obtain amplification.
Moreover, in our calculations we neglect electron- electron collisions, which usually do not affect transpor t proper ties in semiconductors.
Because increasing the numerical aperture has a definite limit, utilizing the smallest wavelength for projection-lithography is the path to progress in semiconductor technology.
The microwave power was evaluated by means of integration of the energy density over the radiation pattern taken using a hot-carrier semiconductor detector.
He expanded his work to calls from other sources and built more complex systems consisting of neurons and semiconductors.
Work on the new technologies - computers, semiconductors, electronics, automation - which had started after the mapping of the twelve-year plan also developed rapidly.
The same structure is a feature of partial differential equations models of semiconductors and ion channels.
