Yes. In electronic devices, semiconductors fulfill a variety of functions, including current filtering - a semiconductor diode only lets current pass in one direction - and signal amplification, using transistors. Transistors have many uses, including for electronic switching. Do some reading on diodes and transistors, while bearing in mind that they use semiconductors.

An insulator is a material that does not conduct electricity. More specifically, it is a material that is chosen to prevent electricity passing from one point to another. Typical examples are the plastic covering on cables, plastic cases around electronic circuits and the body of circuit boards which support copper tracks but keep them isolated from each other.
All wires conduct electricity, since wire is always made of metal, and all metals are conductors. Copper is preferred though, as it has the highest electrical conductivity rating of all non-precious metals. It is also very ductile when annealed, so can be drawn into wire of anything down to sub-millimetre diameters. Other metals are used for other properties. Aluminum wire has a higher conductivity to weight ratio and lower cost, for instance.
Silicon can conduct electricity, but not nearly as well as copper does. The conductivity of silicon depends a great deal on what is mixed with it, because this affects how tightly it holds on to its outer electrons. Silicon is the main ingredient in glass, which does not conduct electricity. Silicon is also used to make semi-conductors, which do conduct electricity, but still not as well as copper does. (That's why they're called semi-conductors instead of conductors.) It is a semiconductor and can be controlled by doping it with Arsenic, Indium, Gallium, etc. to become an insulator or good conductor when applying a voltage across it. For more information see the Related link shown below.
In any metal, the valence electrons (that one might expect to find in the outermost level surrounding each nucleus) are able to move freely throughout the substance. This permits the flow of electricity, which requires that electrons be added at one end and removed at the other.
Metallic bonds are able to conduct electricity only when they are dissolved in a liquid substance or when in molten, this is because these conditions cause the metallic bond to break down and allow the electrons used in the bond to be delocalised and disposited around the molten or liquid. This sea of free electrons is then able to pass through a current and conduct electricity.
semiconductors: other materials which conduct only under certain conditions
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
The connection between a metalloid and a semiconductor is that metalloids are used in electronics as semiconductors. A semiconductor doesn't conduct electricity as well as a metal, but does conduct electricity better than a nonmetal.
o There are some organic compounds that can conduct electricity (organic conductors) salts, solubilized in water or any other solvent that can solubilize them conduct electricity. Molten salts conduct electricity ionized atoms or molecules can conduct electricity
Vetsin is another name for the flavor enhancer MSG. It does not directly conduct electricity, but it is a salt and like other salts when dissolved in water separates into positive and negative ions. These ions are highly mobile in water, thus permitting the solution to conduct electricity.
Bromine is a gas at liquid temperature. It can only conduct electricity when bonded with another metal or element.
Various non-metals can conduct electricity, such as graphite. Graphite is an allotrope of carbon, and it has one electron per carbon atom that is delocalized and not involved in chemical bonding, thus it can carry electric charges. Other non-metallic materials like semi-conductors can also conduct electricity to various degrees. Molten and aqueous ionic compounds like sodium chloride also conduct electricity.
Graphite (an allotrope of carbon) and graphene does conduct electricity whilst other allotropes of carbon such as diamond do not.
Silk, yarn and many other threads used in a satin weave do not generally conduct electricity.
carbon is not a metal and can conduct electricity
pure water does not conduct electricity. the presence of electrolytes in the water is what conducts electricity. the equation for the conductivity (ability to conduct electricity) Conductance = 1/ resistance
No, pure water does not conduct electricity because there are no other solutions present. For the water to conduct electricity, there has to be an electrolyte. Salt water, Tap water, and sugar water do conduct a little electricity because they contain soluble ionic compounds.
