What are the Various Uses of Semiconductor Compounds?
When we hear the word semiconductor, the people who are not that keen in the terms of science may find it not that easy to understand. Most of us have, we can say some knowledge about the words conductors and insulators, if not aware of the complete dynamics. But what is about semiconductor remains to be asked. Is it anything between conductor and insulator, or anything else.
Well, this blog will surely give an apt answer to many questions springing up in your head.
Semiconductors are the materials with electrical conductivity between conductors, and insulators. Of all the elements, just some of them qualify to be used as semiconductor materials. Silicon, selenium, and germanium are to name a few. Amongst them, silicon is the most common semiconductor. It has a number of commercial applications associated with it and is available, fairly easily.
What is a Com¬pound Semi¬con¬duc¬tor?
These are semiconductors made from a minimum of two or more elements. Silicon is made from a solitary element, and so is does not qualify as a compound semiconductor.
Most of the compound semiconductors are from groupings of elements from Group III and V of the periodic table. Further compound semiconductors are made from Groups II and VI. It is also likely to make use of different elements from the same group, to make compound semiconductors for example SiC.
Formerly, compound semiconductors were not that widely used in the commercial applications and high production generally for silicon. These crystals are further hard to grow than silicon. The defect count in the crystal is higher, and the cost of producing the crystal is also on the higher side. Compound semiconductors are also more fragile.
All the factors, which are mentioned here are only for the growth of compound semiconductors, just meant for commercial use.
In recent times, though, the total cost associated with the manufacturing of compound semiconductors has relatively observed a down the hill movement.
But, even with this downward movement, It is still considerably higher than silicon, but the salient properties of these crystals are increasingly important for a number of applications. It is due to their essential material properties; compound semiconductors are able to do all those tasks, that are not possible just with the use of silicon.
We have talked much about these semiconductors having different applications, let’s look at those.
• Consumer electronics have got semiconductor components for example, diodes integrated chips, and transistors.
• These are also a part of the embedded systems. These systems can be termed as small parts of a large machines, controlling the machine and let user interaction. Digital watches, fitness trackers, GPS systems, TVs are some of the examples of embedded systems.
• Some semiconductors can be employed as a cooling agent in some thermoelectric applications.
• Some of those, generally those existing in liquid or amorphous form as a thin-coated film, are able to produce light and are used in OLEDs.
All these varied applications of compound semiconductors have a lot to do with the growing demand for these devices all over the world. The total value of the compound semiconductor industry will reach a value of USD 61,911 million by the end of this decade.
