becsaus of dopping semiconductor is neuraly filled
when n type semiconductor is mixed with p type, majority charge carrier of n type goes to p type and majority of p type goes to n....... this is called as dopping
p-type or n-type semiconductor alone is of very limited use in chips -- you can only make a thin-film resistor or parallel-plate capacitor with it. You also need the opposite type, the n-type semiconductor, to make junction diodes and MOS or bipolar transistors, which are essential components in an integrated circuit. ================================
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
PNP stands forÊjunction transistor having an n-type semiconductorÊ setting between a p-type semiconductor as emitter and a p-type semiconductor as a collector.
This just means that the semiconductor has extra holes in it. On the order of 10^6 I believe.
An intransic material is a material that have been used in doping process.There are two type of intrinsic material n type and p type.

When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.

band diagram of p type semiconductor
In n-type semiconductor, electricity is conducted by NEGATIVE charges (electrons). In a p-type semiconductor, electricity is conducted by POSITIVE charges (holes).
electron
N- Type and P- Type :)
it is like p type semiconductor because when adding impurity its conductivity decreases
