∙ 13y agoA semiconductor is a material with electrical conductivity intermediate between metals and insulators and used in a wide range of electronic devices. Certain crystalline materials, most notably silicon and germanium, have a small number of free electrons that have escaped from the bonds between the atoms. The atoms from which they have escaped possess vacancies, called holes, which are similarly able to move from atom to atom and can be regarded as positive charges. Current can be carried by both electrons (negative carriers) and holes (positive carriers). Such materials are known as intrinsic semiconductors.

∙ 9y agoSemi-conductivity refers to a state of being able to conduct heat or electricity to a certain extent. Such substances are partly used as conductors and partly as insulators.

What do you call a single element semiconductor material such as silicon and germanium?
Intrinsic semiconductivity
What has the author M T Serra written?
M. T. Serra has written: 'Characterization of the semiconductivity of passive films on AISI 304 and 316 stainless steel'
What property of the material used in computer chips makes then useful as switchesnthat turn electricity on and off?
Im pretty sure its semiconductivity [: hope that helpss[: in some switches bimetal bars are used i think
What was the problem with Moore's Law in the future?
For it to continue forever it would require making transistors smaller than a single atom, which is obviously impossible. However long before then it would require making transistors containing fewer atoms than are required for a material to exhibit its bulk properties. Since the property of semiconductivity is a bulk property and transistors require it to operate, while one could try to make transistors that small it is impossible for them to work. However long before then there are issues of practicality that make fabrication of reliable integrated circuits questionable as they get progressively smaller in internal dimensions.

Are non metal more electropositive than a metal?
There are two types of conductors 1- Metals and 2- Electrolytes, the compounds which become ionized in aqueous solution or in molten state are electrolyte so metal is a conductor of electricity but not an electrolyte.
