Semiconductors are present in almost all modern electronics. In fact, Now you read this article on mobile or computer, semiconductors are also included in your mobile or computer.

Today here we know all the applications of semiconductors in daily life or applications of semiconductors in electronics. Can you imagine your life without smartphones, computer, internet, television? For me and most of you says – No!!!!!. Without semiconductors, our life would be much different. All electronics are made by using some semiconductor devices. Semiconductors are in almost everywhere around us.

Semiconductors are the material which it names suggest. The exact middle condition between conductors and insulators. It has some properties like conductors and some properties like insulators. Silicon, germanium, Gallium arsenide are the example of semiconductor materials. Semiconductors have less conductivity than conductors and high conductivity than insulators. Silicon, Semiconductors are generally two types: p-type semiconductor and an N-type semiconductor. By the p-type and n-type semiconductor material, many devices are made like diodes, Transistor, MOSFET, JFET, UJT, and others.

There are decent amount of applications of semiconductors in daily life which we can not able to describe but here I collect some of the everyday uses of semiconductors which I am going to share with you.

Application of semiconductor In daily life

>> Semiconductors are used in solar technology

>> Used in 3D printing machines

>> Temperature sensors which used in air conditioners are made with semiconductor devices.

>> Rice cooker cook perfectly because of semiconductor control temperature precisely.

>> Semiconductors play a central role in the operation of bank ATMs, trains, the internet, communications and other parts of the social infrastructure, such as the medical network used for the care of elderly, among other things.

>> Used in self-driving cars

>> Semiconductor devices are used in computer, calculator, solar plates and other electronics devices.

>> Semiconductors devices are used in microchips which are used in our electronics devices such as the computer, mobile etc. All types of transistor are used in building blocks of logic gates. Transistor and MOSFET are used as a switch in most of the Electrical Circuits. This transistor and MOSFET are build using the semiconductors. Transistor and MOSFET are made up by p-type and n-type semiconductors.

After knowing the everyday uses of semiconductor here we see why semiconductors are used in daily life applications.

Why semiconductors are used?

If I want to give a short and sweet answer then semiconductors are used because we can control the conductivity of semiconductors easily. It is not easy to change the conductivity of the conductor and insulators. We can change the conductivity of semiconductor material by doping. By doping phosphorus in silicon semiconductor it becomes n-type semiconductor and by doping boron in silicon semiconductor it becomes p-type semiconductors. By doping, we can increase the conductivity of semiconductor material.

Hope now you understand why semiconductors are used instead of conductors and semiconductors.

Advantages of semiconductors

Here are some advantages of semiconductors which makes semiconductor useful in our everyday life. :

>> Semiconductors have no requirement of filament heating so semiconductors device such as transistor takes place in almost all vacuum tube applications. Because of the filament vacuum tube requires heat for operation.

>> Semiconductor devices are solid-state devices. So they are shockproof.

>> Semiconductor devices are so small in size which makes it easily portable.

>> It has Less cost than a vacuum tube.

>> Semiconductor devices require less input power for operation.

>> During the operation period, it does not make any noise. So we can see semiconductor devices are noise-free devices.

>> Semiconductor materials have a longer lifespan. They have an almost unlimited life.

Applications of semiconductors in industry

Day by day with the increase in technology semiconductor requirement is also going to improve. As per industry demands many new devices are discovered in nowadays with the help of semiconductor materials. Without transistor and integrated circuits, our modern life would be very difficult. The properties of semiconductor materials make possible numerous technological wonders, including transistors, microchips, solar cells, and LED displays. With the microprocessor, we can control the operation of car, trains and space vehicles. The microprocessor is made up by numerous transistor and other controlling devices which made up by the semiconductor material.

Semiconductor device materials

As per above, we see silicon. Germanium and Gallium arsenide is the example of semiconductor material. The silicon (Si) is the most widely used semiconductor material. It’s having lower raw material cost and relatively simple process. Its useful temperature range makes it currently the best compromise among the various competing materials. Silicon used in semiconductor device manufacturing is presently fabricated into bowls that are large enough in diameter to allow the manufacture of 300 mm (12 in.) wafers.

Germanium ( Ge ) was widely used semiconductor material in past. Recent silicon semiconductor is used in most applications. Thermal sensitivity of germanium is comparatively low than a silicon semiconductor. So silicon is going to first preferred semiconductor.

Gallium arsenide (GaAs) is also a semiconductor device which is widely used with high-speed devices. This semiconductor is more expensive than other semiconductors.

Which devices are made with semiconductors?

Semiconductors are useful for making extremely small electronics device with which evolution of modern electronics possible. With the semiconductors two terminals, three terminals and four terminal devices are made.

Two terminal devices

  • Diode – which is made up by two semiconductors. It made with a p-n junction. The diode only passes current through it when it is in forwarding bias. Diodes are used rectifier circuits which converts A.C to D.C.
  • Gunn diode
  • IMPATT diode
  • Laser diode
  • Zener diode
  • Schottky diode
  • PIN diode
  • Tunnel diode
  • Light-emitting diode (LED)
  • Photo transistor
  • Photocell
  • Solar cell
  • Transient-voltage-suppression diode
  • VCSEL

Three-terminal devices are

  • Bipolar transistor – Transistor is three terminal device. Base, collector, and emitter. Transistors are used in switching applications and as an amplifier.
  • Field-effect transistor
  • Darlington transistor
  • IGBT
  • Unijunction transistor
  • Silicon-controlled rectifier
  • Thyristor
  • TRIAC

Four-terminal devices are

  • Photocoupler (Optocoupler)
  • Hall effect sensor (magnetic field sensor)

conclusion

here we know all most all applications of the semiconductor in daily life. We list out all applications and uses of semiconductors above, We saw semiconductors are everywhere in our life or industry. Semiconductors devices such as the transistor, MOSFET etc are extremely used form making smaller electrical circuits. If you have any questoin related to this article kindly comment below,
