Difference Between p-type and n-type Semiconductor

The impurity added in p-type semiconductor provides extra holes known as Acceptor atom, whereas in n-type semiconductor impurity provides extra electrons and termed as Donor atom. In a p-type semiconductor, the majority carriers are holes, and the minority carriers are electrons.

Which is better p-type or n-type semiconductor?

Since the minority carriers are electrons and holes in p-type and n-type semiconductors, respectively, the order of increase in electron density in p-type semiconductor and hole density in n-type one are more sensible than increase in hole density in p-type semiconductor and electron density in n-type one, respectively ...

What is difference between n-type and p-type semiconductor explain with the help of energy band diagram?

Bands for Doped Semiconductors

In n-type material there are electron energy levels near the top of the band gap so that they can be easily excited into the conduction band. In p-type material, extra holes in the band gap allow excitation of valence band electrons, leaving mobile holes in the valence band.

What is the difference between the p and n-type silicon?

The main difference between p-type and n-type solar cells is the number of electrons. A p-type cell usually dopes its silicon wafer with boron, which has one less electron than silicon (making the cell positively charged). ... N-type cells are in turn more efficient and are not affected by light-induced degradation (LID).

What is p and n-type?

In n-type silicon, the electrons have a negative charge, hence the name n-type. In p-type silicon, the effect of a positive charge is created in the absence of an electron, hence the name p-type.

What is P-type material?

A p-type semiconductor is an intrinsic semiconductor doped with boron (B) or indium (In). Silicon of Group IV has four valence electrons and boron of Group III has three valence electrons.

What are the applications of P and N semiconductors?

Diode is a combination of n-type and p-type semiconductors extensively used as a rectifier. Transistors are manufactured by keeping a layer of one type of semiconductor between two layers of another type of semiconductor. npn and pnp type of transistors are used to detect or amplify radio or audio signals.

What are the types of semiconductor?

There are two types of extrinsic semiconductors: p-type (p for positive: a hole has been added through doping with a group-III element) and n-type (n for negative: an extra electron has been added through doping with a group-V element).

What is meant by n type and p type semiconductor?

p-n junction diodes are made up of two adjacent pieces of p-type and n-type semiconducting materials. p-type and n-type materials are simply semiconductors, such as silicon (Si) or germanium (Ge), with atomic impurities; the type of impurity present determines the type of the semiconductor.

How are n type and p type semiconductor formed?

Pentavalent impurities Impurity atoms with 5 valence electrons produce n-type semiconductors by contributing extra electrons. Trivalent impurities Impurity atoms with 3 valence electrons produce p-type semiconductors by producing a "hole" or electron deficiency.

Is boron n-type or p-type?

Boron is a p-type dopant.

How do you know if type is N or P?

If the dopant has more electrons in the outer shell than the semiconductor material, it's going to be n-type, and with less electrons in the outer shell, it's p-type.

Is P-type semiconductor positively charged?

P-type semiconductors

The term p-type refers to the positive charge of a hole. As opposed to n-type semiconductors, p-type semiconductors have a larger hole concentration than electron concentration. In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers.
