In general, metals are shiny, reflecting most of the light that strikes them. They are malleable and ductile (that is, they will bend under pressure and are not brittle). They have a broad range of melting temp
That’s because metal is a great conductor of electricity. (In fact, so is the human body, which is why you can sometimes pass the shock on to someone else.) The opposite of a conductor is an insulator, which impedes the flow of electrons from one material to another. Rubber is a gr...
Grinding is an intricate abrasivemachining processinvolving an abrasive wheel as a cutting tool. It’s renowned for its ability to produce very fine finishes and extremely accurate dimensions on metal parts. Grinding involves a rotating grinding wheel made of abrasive particles, which act as miniature...
Metals can burn or melt in a fire, depending on the temperature and type of metal. Some metals such as sodium and magnesium will burn, even explosively, in the presence of oxygen and a flame. There are many different kinds of metal and this is what you need to know about how and why...
A complementary metal-oxide semiconductor (CMOS) is thesemiconductortechnology used in most of today's integrated circuits (ICs), also known aschipsormicrochips. CMOS transistors are based on metal-oxide semiconductor field-effect transistor (MOSFET) technology. It is called complementary because each ...

The completed chip gets protective packaging and metal connectors and is ready for use. Chip on Circuit Board The packaged chips are mounted onto circuit boards to begin working inside your electronic devices. It’s an intricate process, but the complexity and dedication to quality allow these chi...
Name the four common halogens and tell the normal phase of each. Which one is the most reactive of all elements? What is an ionic bond? What type of substance form ionic bond? Classify each element as an alkali metal, alkaline earth metal halogen, or noble gas. A) F B) Sr C) K ...
Semiconductor materials include – Silicon,antimony, arsenic, boron, carbon, germanium, gallium arsenide, selenium, silicon carbide, sulfur, tellurium, oxides of most metals. What is Superconductor? Superconductor is an element, inter-metallic alloy, or a compound that conducts electricity without resist...
An FET also has three terminals -- source, drain and gate -- which are analogous to a BJT's emitter, collector and base, respectively. In the FET, the n-type and p-type silicon layers are arranged differently from those of the BJT. They are also coated with layers of metal and oxide...
