What is a semiconductor?

Types of semiconductor in Hindi: electronic equipment whether computer You must have known about HO such as diodes, transistors, integrated circuits, etc., all of them are made from a special material called semiconductor or semiconductor.

but do you know semiconductor what Is (What is Semiconductor in Hindi), semiconductor how many type Of would have been Huh, semiconductor Of Property what Huh, semiconductor of Use Where? Would Is, semiconductor Of Advantages And Harm what Huh,

If you want to know the answer to all such questions, then definitely read this article till the end. Through today’s article we will give you Semiconductor what is in hindi Will give complete detailed information about. So let’s start this article without taking much of your time.

What are Semiconductors

There are some substances in nature that are good conductors of electricity, that is, when they come in contact with electricity, they get current. And there are also some such substances which are corrosives of electricity, when such substances come in contact with electricity, they do not get current.

What is a semiconductor, its types and uses (Semiconductor in Hindi)

But apart from this, some such substances are also present in our nature in which the properties of both good conductor and non-conducting matter are found. Such materials are called semiconductors. semiconductor electronic devices such as diode, Transistor, integrated circuit Used in construction etc.

Definition of Semiconductor

We can define semiconductors as follows:

Semiconductors are materials that have the properties of both a good conductor and a bad conductor.

According to the concept of energy bands, semiconductors at room temperature are those materials –

  • In which the conduction and connective closure are partially filled.
  • The forbidden energy band between them is very narrow. Of the order of about 1 electron volt.

Example of Semiconductor

Some of the major semiconductors are:

  • silicone
  • germanium
  • arsenide
  • gallium

Properties of Semiconductor

Some of the special properties of semiconductors are as follows:

  • The resistivity of a semiconductor material is greater than that of a non-conducting material and less than that of a conductor.
  • Semiconductors have negative temperature coefficient of resistance i.e. with increase in temperature the resistance of the semiconductor decreases and the electrical conductivity increases.
  • When an impurity of a suitable metal is added to the semiconductor, the current properties of the semiconductors change. That is, their conductivity becomes more or less.
  • When semiconductors are in their natural state, they behave like poor conductors, but with the help of some technology, current is flown through semiconductors. such as through doping technology.
  • The conductivity of semiconductors can also be changed by an externally applied electric field or light.

Types of Semiconductor

There are mainly two types of semiconductors –

  • Intrinsic Semiconductor
  • Extrinsic Semiconductor
Types of Semiconductor in Hindi
type of semiconductor

#1 Intrinsic Semiconductor

No impurities are found in the intrinsic semiconductor. They are made of only one type of element. Germanium and silicon are the most common types of intrinsic semiconductor elements. Intrinsic semiconductors have very low electrical conductivity.

#2 Extrinsic Semiconductor

When a small amount of a metal impurity is mixed in a semiconductor material, the electrical conductivity of the semiconductor material increases. The semiconductor made in this way is called extrinsic semiconductor.

For example, when an impurity of a suitable metal is added to germanium or gallium, their conductivity increases.

The process of adding metallic impurity in semiconductors in this way is called doping and this technique to increase the conductivity of semiconductors is called doping.

There are also two types of extrinsic semiconductors –

  • n Type Semiconductor
  • p Type Semiconductor

What are n Type Semiconductors

When an impurity of 5 valence atom is added to germanium or silicon, it replaces one atom of germanium.

4 out of 5 electrons of impure atom form valence bonds one by one with 4 electrons of germanium and 5th electron gets separated from impure atom and starts moving freely inside the crystal. And it is this free electron that acts as a charge carrier.

In this way, adding impurity of the metal to pure germanium increases its conductivity. The semiconductor made in this way is called n-type semiconductor. In n Type Semiconductor the charge carriers are of negative charge.

What are p-type semiconductors

When an impure metal with 3 valency is mixed in germanium or silicon, then 3 electrons of the impure metal form valence bonds with each electron of the nearest 3 electrons of germanium.

One electron of germanium is not able to form a bond, so it remains vacant and this vacancy is called a hole. On applying an electric field from outside, the electron nearest to the coater comes to the coater, due to which the nearest electron becomes vacant and there is a cavity.

In this way, the core starts moving from one place to another inside the crystal, opposite to electricity. The semiconductors made in this way are called p-type semiconductors. The charge carriers in p-type semiconductors are positively charged.

Semiconductor Device

Some of the semiconductor devices are as follows –

  • p – n junction diode
  • photo diode
  • light emitting diode
  • Transistor

Uses of Semiconductor

  • Semiconductors are used in many types of electronic devices.
  • Semiconductors are used to make transistors, diodes, integrated circuits, etc. devices.
  • Semiconductors are also used in making electrical systems, power transmission.
  • Semiconductors are also used to make auxiliary devices in optical sensors.

Advantages of Semiconductor

Semiconductors have the following advantages:

  • Semiconductors do not need to be heated, as there is no filament in semiconductor devices.
  • Semiconductor devices start working immediately when the circuit is turned on, because they do not need to be heated.
  • Semiconductor devices require low voltage.
  • Semiconductors are cheaper than vacuum tubes.

Disadvantage of Semiconductor

  • Semiconductor devices make more noise than vacuum tubes.
  • Semiconductors are unable to tolerate more power than vacuum tubes.
