In summary: Hi,The junction is where the two types of semiconductors meet. They work together because the P-type semiconductor has a higher concentration of holes than the N-type semiconductor.

Hi,
straight away to semiconductors. My first doubt is about why semiconductor materilas are used in making up the diodes or in any other design. why not with conductors.

if you did not use doping with semiconductors then is it possible to make conduction between P-type and N-type. first why we choosen semiconductor devices.

Hi,
this one link gives all the information you need (i hope you may know this link):

Hi,
I know the back ground theorey of semiconductor and conductor before regrading bandgap and doping.
But my doubt is how they got the idea of only semiconductor can be useful for making up of diodes and transistors or may other stuff. I don't know how they are very useful in these areas.

The two parts in bold are in direct contradiction with each other. Learn more about semiconductors and you'll find out how and why they are useful. Your question is far too general.

For starters, what is your current education level?

edit: Here is a non-technical perspective on the history of semiconductors: http://www.computerhistory.org/semiconductor/timeline.html. I haven't read all of it, so I don't know if it is 100% accurate.

1. The charge density in the semiconductors are controllable and hence the current in the devices can be controlled using voltage pulses which is not possible in conductors.

2. The two types of charge carriers is possible only in semiconductors not in conductors which is critical for the diode formation.

I am looking for such kind of information, thank you so much...

Hi,
It is already given in detail in the link which I showed you. It is just your inability to read them.
cheers.

Hi,
P-type semiconducor is formed with doping of aliminium to silicon and it creates one hole left after bonding. Opposite, N-type type is formed due to dpoing of phosphorous to silicon which creates negative semiconductor. But my doubt regards is there any materials(conductor) can behave as same fashion. if the two prepared semiconductors(P and N) attached together and forms diode or any other device then why they are need 0.7V for conduction and regards junction of the diode, is it the name what we generally used at comabination of hole and electron or there is any theorey behind that "junction".
 

What are semiconductors and conductors?

Semiconductors and conductors are types of materials that have different levels of electrical conductivity. Conductors are materials that allow electricity to flow easily, while semiconductors have a moderate level of conductivity.

What are the main differences between semiconductors and conductors?

One of the main differences between semiconductors and conductors is their ability to conduct electricity. Conductors have a high level of conductivity and allow electricity to flow easily, while semiconductors have a moderate level of conductivity and can be controlled to conduct or not conduct electricity.

What are the applications of semiconductors and conductors?

Conductors are commonly used in electrical wiring and circuits, while semiconductors are used in electronic devices such as computers, smartphones, and solar panels. Semiconductors are also used in the production of transistors and diodes.

How are semiconductors and conductors different at the atomic level?

The atomic structure of semiconductors and conductors is different. In conductors, the electrons in the outermost energy level of the atoms are loosely bound and can easily move, allowing electricity to flow. In semiconductors, the outermost energy level is partially filled, making them poor conductors of electricity.

Can a material be both a semiconductor and a conductor?

Yes, some materials can exhibit both conductive and semiconductive properties. These materials are called semimetals or metalloids and include elements such as silicon, germanium, and arsenic. They can be manipulated to behave as either conductors or semiconductors depending on their composition and structure.
