explain the doping level of a transistor?

Answer 1

its called a 'sandwich' type doping.It may have 2 types :
npn or pnp.
p---> p-type semiconductor
n--->n-type semiconductor

Answer 2

The material used to produce the junction in a transistor starts out as an insulator because it is a crystal with a tightly organized lattice structure and no free electrons.

However, if another materials is added (doped) that has a characteristic which enables it to join the crystalline structure - but has an "extra" electron which is "shared" by the adjacent molecules, the material will become a semi-conductor. This is a material that will become a conductor if the proper polarity and voltage force is sufficient to overcome the electrically negative potential of the "doped" crystal due to an excess of "extra" electrons which are held in place by the crystalline structure - usually around six tenths of a volt in silicone.

If these materials are stacked, the center junction may be used to "control" the conduction of electrons through the transistor, allowing it to utilize a very small voltage potential to control a much larger current flow. This can be a simple switch (on/off) or an amplifier (varying the amount of output directly proportional to a much smaller input)

Answer 3

There are two type of dopings n type and p type. n type has electrons as carrier of charge and p type have hole as carrier. there are two types of ttransistor. npn and pnp. it is w e can call a sanwitch. on top we have emmiter which is highly doped than base which is nominal doped and collector which is least doped if we talk about fraction or percentage of doping.
