Why for making an n-type semiconductor silicon or germanium is doped with only fifteenth group element like phosphorus?

in silicon or germanium, the valence shell contain 4 electrons. in order to attain stability,
they need 4 more electrons, so we doping it either with trivalent or pentavalent
impurities. if we are doping semiconductor with any of these, we call it as an extrinsic
semiconductor if we are using pentavalent impurity such as phosphorous, there will be an
extra electron,which will go to conduction band. we know electron has negative charge
therefore we call it as n-type semiconductor

Is phosphorus a mixture?
No, phosphorus is an element.
What type of element is phosphorus?
What type of element is phosphorus
Is phosphorus a chemical?
If phosphorous occupie the gallium sites, it would be n type semiconductor since it has more number of valence electrons than gallium and if it occupie the sites of the arsenic sites there is no change since the valency of arsenic and phosphorous be the same
Is phosphorus a polyatomic molecule?
No. phosphorus is a basic element.
What is the 15th element?
The 15th element is phosphorus
What do you call a single element semiconductor material such as silicon and germanium?
Intrinsic semiconductivity
How do you construct an n type semiconductor?
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
Why geranium is known semi conductors?
A geranium is a flower, and not a semiconductor. The element Germanium, however, is a semiconductor, which means it has an electrical conductivity somewhere between that of a metal and an insulator.
Is germanium an alloy?
Germanium (Ge) is an chemical element, with atomic number 32. It can form a number of alloys, notably a silicon-germanium alloy, an important semiconductor with utility in high speed integrated circuitry in electronics.
Which element is used as a semiconductor?
Elements of group 4a are used as semi-conductorse.g. silicon,germanium etc.
Is germanium a element?
Yes, germanium is an element.
What is an element that shares the properties of metals and nonmetals?
An element that has properties of both metals and non-metals is called Metalloid. Example is Germanium.
Is germanium a compound element?
Germanium is an element, not a compound.
Is phosphorus a mixture a compound or a element?
Phosphorus is an element.
Is germanium a man made element?
Germanium (Ge) is a natural element.
What elements are semiconducter?
One element that is semiconducter is Silicon. 2nd answer: One common element used to manufacture a semiconductor is silicon. Germanium has also been widely used, and is more sensitive to tiny voltage changes than silicon. The compound gallium arsenide is very common in the manufacture of semiconductor material, as well.
Which element is a semi-conductor of electricity?
Most conductors conduct both heat and electricity well. A semiconductor is a conductor whose resistance is between that of a conductor and an insulator. An example of a semiconductor is silicon which is used in electronic appliances
