1It is required that such insulator (绝热体) ___ a heat resistant material. A. must be made of B. should be made of C. will be made of D. would be made of C. D 2It is required that such insulator (绝热体) () a heat resistant material. A. must be made of B. should ...
A semiconductor device having a logic section and a memory section that are formed on the same semiconductor chip, including: a first transistor formed in the logic section and having gate electrodes and source and drain regions, and a second transistor formed in the memory section having gate ...
The word dielectric consists of two parts, first the prefix “dia” which is a Greek word means “through,” so dielectric is a material that allows the passage of electric flux or electric field but not allows the flow of all types of charge carriers[46,47]. Thereforedielectric materialsar...
(i) It may be preferred to solder to a particular coating rather than to the actual base metal surface to prevent excessive dissolution of the latter. For example, the dissolution of a nickel coating is significantly slower than is that of gold or copper in tin-based solders (Bader 1969, ...
There are several materials and elements used to make semiconductor. The basic requirement is that the material should not be a very good conductor of electricity, nor should it be a very bad conductor of electricity. Its properties can be changed by adding or removing atoms / impurities. ...
aSemiconductor-on-insulator structure used for applications in electronics, optics and opto-electronics comprises a semiconductor material part and an electrically insulating part that are interlocked 用于被连结的应用的半导体在绝缘体结构在电子、光学和光电子学方面包括一个半导体物质零件和一个电子绝缘的部分 ...
a consequence of such transition, the material is able to reflect the incoming infrared radiation and reduce the indoor solar gains[98]. The main drawbacks of such technology lie on the fact that generally, materials like VO2have a high transition temperature, i.e., about 68°C, and a ...
is referred to as reinforcement, while the less stiff and weaker phase is continuous and is known as matrix. The properties of a composite depend on the properties of the constituents, geometry and distribution of the phases. The phases of the composite have different roles that depend on the...
This alloy is brittle and not flexible and cannot be formed into a thin sheet by rolling, forging or swaging, so that it was used either bulk-like body in a low frequency region or its use is limited to a dust core in a high frequency region. There was demerit that a fine cracking...
