When an n-type semiconductor is further doped with pentavalent atom, four of the atoms are tiedly bond through the process of covalent bond and one electron is weakly bound and free to move as the temperature rises.

∙ 12y agothe electrons from the n type material will fill the holes on the p type material creating a depletion zone.The depletion zone acts as a barriar between the two materials causing electrons to stop filling the holes and the depletion zone to stop growing.What happens if you add current depends on the way it goes.If n type connects to + and vise versa, the electrons and holes will go to the ends, increasing the depletion zone.If you add n type to - and p type to + then the electrons and holes go to the middle, shrinking the depletion zone.You have now found out that you can turn AC current to DC current with this combanation called a diode, in fact you can use only four, but that's for you to find out.

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 is formed when part of a material is doped n-type and part of it is p-type?
if the two parts are next to each other, a junction. if not, nothing.
What is p type silicon substrate?
Wafers are formed of highly pure defect-free single crystalline material. Donor impurity atoms, can be added to the molten intrinsic material changing it into n-type or p-type extrinsic semiconductor.
Is p-type material positively charged?
The net charge on n-type and p-type meterials is zero because the r formed by the combination of diferent chemists...
What is the depletion layer in a semi conductor?
in correct sense it is not the layer but the region around the metallurgical junction which is depleted of charge carriers .in this region an internal electric field exist which counter balance the diffusion of electron and hole around the junction . basically the main reason for the formation of depletion region is the concentration gradient across metallurgical junction of p-n semiconductor.

How are P- and N-type materials made?
how can i make p type n type material
How the n type and p type semiconductor is joint without adding any impurity?
doping
Use of p-n type material?
Diodes.
How n type and p type material made?
pentavalent and trivalent atoms
What is bulk resistivity?
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
How are N type semiconductors formed?
N-type semiconductors are a type of extrinsic semiconductor where the dopant atoms (donors) are capable of providing extra conduction electrons to the host material (e.g. phosphorusin silicon). This creates an excess of negative (n-type) electron charge carriers.
Do a slab of n type material carry a net negative charge?
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
What is the net charge on intrinsic N type material?
first of all un-doped semi-conductor is said to be intrinsic semi-conductor so, there is no discussion of either N-type or P-type
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.
How could a n type semiconductor be produced from pure germanium?
just by adding pentavalent kind of material
What is a description of Simple P-N junction diode?
The junction formed by the combination of a P- type & N-Type material in known as PN jn diode. It is used as a switch as well as a rectifier.
