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

∙ 10y agoYou mustn't forget the atomic nuclei. With p-type doping, the doping atoms will have 3 electrons with which to bond, instead of the 4 that silicon has, but the doping atom will also have one fewer proton in its nucleus (assuming simplest case) than silicon.

∙ 10y agoDoping of pentavalent (five valence electrons) atoms to tetravalent (four valance electrons) atoms produce N type semiconductors.
Both pentavalent and tetra valent atoms are neutral. (Atoms always are neutral unless they loose electrons: once they loose electrons, they are no more atoms and they are called ions)
In doping we add only atoms and since they are neutral they are neutral after doping also.
The total number of positive charges and negative charges in the N type semiconductor remains the same even after doping. Hence the N-type semiconductors are neutral till they loose some positive or negative charges.
Though metals are having many free electrons, they are always neutral till they loose electrons.
Similarly though N type semiconductors have free electrons they are neutral till they loose some electrons.
Mere presence of free electrons does not make them negatively charged materials.
Similarly in P- type semiconductors, mere presence of free holes does not make them positively charged materials.
Only when charges are removed away from the materials they become charged.

How is p type semiconductor formed?
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. ================================
Why p type semiconductor has majority charge carrier as hole?
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.
What is pnp resistor?
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.
What is a p plus type semiconductor?
This just means that the semiconductor has extra holes in it. On the order of 10^6 I believe.
What you understand by the term intrinsic semiconductor and how an intrinsic semiconductor is turned into either a p type or an n type material?
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.

What are the examples of p-type semiconductors?
Examples of p-type semiconductors are silicon doped with gallium and silicon doped with boron. P-type semiconductor refers to positive type doping of semiconductor.
IS indium a p type semiconductor?
yes
Diffrentiate 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.
Why p type semiconductor has majority charge carrier as hole?
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.
What is the term for a semiconductor that is missing electrons?

Draw energy band diagram of n type semiconductor?
band diagram of p type semiconductor
What is pnp resistor?
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.
How are P- type semiconductor materials formed?
A (P type) semiconductor is formed by adding impurities, which provide extra holes.
What is an explanation of n-type and p-type semiconductors?
In n-type semiconductor, electricity is conducted by NEGATIVE charges (electrons). In a p-type semiconductor, electricity is conducted by POSITIVE charges (holes).
