Most semiconductors are elements with 4 valence electrons:
- carbon as either diamond or nanotubes, still has process problems
- silicon, most preferred now
- germanium
There are also binary semiconductors made of alloys of elements with 3 & 5 valence electrons:
- gallium arsenide is used in some very high speed electronics
- aluminum indium gallium phosphide is used in some LEDs and solid state LASERs
- etc.
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 electronics
- selenium is used in light sensitive drum in photocopiers and laserprinters
- lead sulfide (galena) used in crystal radios
- etc.

What are p type 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.
What is the meaning of semiconductors?
Oversimplifying it significantly "not quite conductors". These are materials whose ability to conduct electricity is between conductors and insulators but can be very precisely controlled by doping with other elements as impurities, allowing the construction of electronic devices that can: control the direction of current flow, amplify signals, act as switches, perform boolean logic functions, etc. These materials can be classed as elemental semiconductors, binary semiconductors, other semiconductors. The elemental semiconductors are elements with 4 valence electrons that are not metals (e.g. silicon, germanium), the binary semiconductors are "alloys" of two elements: one with 3 valence electrons and the other with 5 valence electrons (e.g. gallium arsenide, indium phosphide), other semiconductors can be elements (e.g. selenium) compounds (e.g. galena, copper oxide) or complex "alloys" of several elements (e.g. gallium arsenide phosphide, aluminum gallium indium phosphide). The term semiconductors is also used to refer to the electronic devices mades of these materials.
What is semiconductor die?
it refers to a grow silicon seed that is used to grow the final semiconductors
Why N Type Semiconductors are preferred over P Type Semiconductors?
since n type semiconductors have high mobility for electrons, they are preffered over ptype
Breakdown phenomenon of semiconductors?
Ther are generally Two types of Breakdown Phenomenons comes into picture. Namely- 1. Avalanche Breakdown 2. Zener Breakdown.
What elements are semiconductors?
Silicon and germanium are among the widely used semiconducting elements.
Which group of the periodic table of elements is used to make semiconductors?
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.
What are the types of intrinsic semiconductors?
The types of intrinsic semiconductors are mainly: silicon & germanium
Which type of element is used as semiconductors?
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.
What class elements are semiconductors?
Metalloids
What three elements that are used in semiconductors?
Silicon is the most common element used in semiconductors due to its abundance and well-understood properties. Germanium is another element used in semiconductors, although less commonly than silicon. Arsenic and phosphorus are often incorporated as dopants to introduce either additional electrons (n-type doping) or electron vacancies (p-type doping) in semiconductors.
Are non metals semiconductors?
Metals are conductors. Semiconductors are usually non-metals or metalloids.
Pentavalent elements are added to intrinsic semiconductors elements to produce what type?
N
What are the semiconductors in the periodic table?
Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.
Elements that are intermediate conductors of heat and electricity?
semiconductors
The elements in the Periodic Table which are semiconductors are called?
metalloids
What are p type 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.
