silicon and germanium
Not all crystalline materials are semiconductors.
Intrinsic means no dopants. (a term used in semiconductors) So it means the same as pure.
LED is short for Light Emitting Diode. It is a special type of diode that emits light when it is forward biased. Diodes are made using N doped and P doped semiconductors(not intrinsic/pure.) They form a junction that allows the system to act as a diode. So in short, no. However these doped semiconductors were made using pure(intrinsic) semiconductors. Therefore depending on how far you trace back the process the semiconductors were once intrinsic. So depending on how you look at it, yes.
No, nonmetals tend to be insulators. Some (e.g. carbon) are poor conductors. Semiconductors (e.g. silicon and germanium) in their pure form are insulators but when doped with the right impurities can conduct as good as metals. This is why they are called semiconductors.
by adding pentavalent impurity in d pure semiconducters (like intrinsic semiconducters) is called n type semiconducters
Application of semiconductors
a pure semiconductors with a valency of three doped with a trivalent element is called p-type and a pure semiconductors with a valency of three doped with a pentavalent element is called n-type
Semiconductor raw materials like silicon, germanium, and selenium are the purest substances that you will have a chance to encounter. However the process of making semiconductor devices deliberately contaminate the semiconductor with controlled amounts of various impurities. Other semiconductors like gallium arsenide and the semiconductors used in LEDs are alloys. Other semiconductors like cadmium sulfide and lead sulfide (galena) are compounds.
Transistors are made out of semiconductors, yes.
