The difference between the p-type and the n-type semiconductor is that the p-type semiconductor has more holes than electrons while the n-type semiconductor has more electrons than holes.

∙ 13y agoP-type semiconductor: It is the sub type of extrinsic semiconductor.Extrinsic means impure semiconductor.That is the impurities are added in this.there are two types of impurities,which are Donar i.e. penta valant impurity and another is Acceptor impurity i.e. Trivalant impurity. The p-type semiconductors are formed by adding acceptor impurities i.e. Galium,Boron,Indium,e.t.c. Suppose Galium is added to the Silicon atom. Then Silicon in pure semiconductor i.e. it has 4 valance electrons whereas Galium has 3 valance electronics in it. So when Galium is added to Silicon the 3 valance electronics of galium atoms forms co-valant bond with the three neighbouring Silicon atom.then one co-valant bond should break due to theabsence of one electron of Galium atom and hole should be created. Thus in P-type semiconductors Holes are created.
N-type semiconductors:
In order for our silicon crystal to conduct electricity, we need to introduce an impurity atom such as Arsenic, Antimony or Phosphorus into the crystalline structure making it extrinsic (impurities are added). These atoms have five outer electrons in their outermost co-valent bond to share with other atoms and are commonly called "Pentavalent" impurities. This allows four of the five electrons to bond with its neighbouring silicon atoms leaving one "free electron" to move about when an electrical voltage is applied (electron flow). As each impurity atom "donates" one electron, pentavalent atoms are generally known as "donors".
Antimony (symbol Sb) is frequently used as a pentavalent additive as it has 51 electrons arranged in 5 shells around the nucleus. The resulting semiconductor material has an excess of current-carrying electrons, each with a negative charge, and is therefore referred to as "N-type" material with the electrons called "Majority Carriers" and the resultant holes "Minority Carriers". Then a semiconductor material is N-type when its donor density is greater than its acceptor density. Therefore, a N-type semiconductor has more electrons than holes.

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. ================================
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 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.
What is the majority carrier in an n type semiconductor?
p-type majority carriers are holes n-type majority carriers are electrons
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?

Difference between intrinsic and exterinsic semiconductors?
Answer An intrinsic semiconductor is a pure semiconductor. An extrinsic semiconductor is doped with trivalent of pentavalent impurities. semiconductors allow only a little amount of electricity to pass through them.they are of two types - n type and p typeAre made of the semiconductor material in its purest from
What is an n-type semiconductor?
An n-type semiconductor is a type of material that has been doped with impurities to increase the number of free electrons, giving it a negative charge. This excess of electrons allows the material to conduct electricity more easily. N-type semiconductors are commonly used in electronic devices due to their ability to carry current.
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.
When silicon is doped with phosphorous what type of semiconductor results?
it would be a n-type semiconductor because phosphorus has more valence electrons than silicon does.
What is NMO?
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.

How are N-type semiconductor used in semiconductor diode?
p-type semiconductor is obtained by carrying out a process of doping that is by adding a certain type of atoms to the semiconductor in order to increase the number of the free charge carriers.
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).
What is abbreviation NMOS?
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.
What is term for a semiconductor that contains extra electrons?
N-type semiconductor contains extra electrons.
