metalloids
Semiconductors are elements belonging to the metalloid group on the periodic table, with properties that lie between those of metals and nonmetals. Silicon and germanium are the most common semiconductors used in electronic devices due to their ability to conduct electricity under certain conditions.
No, compound semiconductors do not behave as intrinsic semiconductors because they have different band structures due to the combination of different elements. Compound semiconductors have unique electrical properties that make them suitable for specific applications that require different performance characteristics compared to intrinsic semiconductors.
Metalloids or semiconductors
No, semiconductors are not noble gases. Semiconductors are a type of material that can conduct electricity under certain conditions, while noble gases are a group of non-reactive elements in the periodic table.
Silicon and germanium are among the widely used semiconducting elements.
Group 14 elements, mainly silicon or germanium are semiconductors. If they are dopped with group 13 elements such as gallium / indium or with group 15 elements such as arsenic / antimony, then the conducting ability increases.
Commonly doped silicon is used to make semiconductors, but advancements in organic electronics now mean that semiconductors can be made from molecules made from elements such as carbon, hydrogen, oxygen, sulphur, nitrogen and a few others.
Metalloids
Metals are conductors. Semiconductors are usually non-metals or metalloids.

Most semiconductors are elements with 4 valence electrons:carbon as either diamond or nanotubes, still has process problemssilicon, most preferred nowgermaniumThere are also binary semiconductors made of alloys of elements with 3 & 5 valence electrons:gallium arsenide is used in some very high speed electronicsaluminum indium gallium phosphide is used in some LEDs and solid state LASERsetc.There are also less commonly used semiconductors used in special purpose applications:copper oxide used to be used in high voltage rectifiers in low cost vacuum tube electronicsselenium is used in light sensitive drum in photocopiers and laserprinterslead sulfide (galena) used in crystal radiosetc.

semiconductors
P type semiconductors have been doped with trivalent elements, causing them to conduct via "hole" flow. N type semiconductors have been doped with pentavalent elements, causing them to conduct via electron flow.
Silicon based semiconductors are the most commonly used semiconductor material in calculators. Silicon semiconductors are also extensively used in computers.
