What is the most commonly used material in the manufacturing of semiconductors?

The material most frequently used in semiconductors is Silicon (chemical symbol = Si). Silicon is the second most abundant element on earth after Oxygen.

Why do we use semiconductor instead of conductor or insulator in electronic device?

We use semiconductor because we wish a material that you can control easily the conductivity. And for this purpose, semiconductors are the best one. It is not so easy to control the conductivity of isolator and conductors. The transistor works as a switch, that is close (low resistance) or open (high resistance).

Why germanium is a good semiconductor?

Germanium atoms have one more shell than silicon atoms, but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell. As a consequence, both materials readily constitute themselves as crystal lattices. Substituted atoms alter the electrical properties.

Why semiconductors are important in electronics?

Semiconductors are especially important as varying conditions like temperature and impurity content can easily change their conductivity. The combination of various semiconductor types together generates devices with special electrical properties, which allow control of electrical signals.

Why do we prefer Si material in semiconductors for different electronic components?

Silicon is used for electronic devices because it is an element with very special properties. One of it’s most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others. Silicon is also an abundant element on Earth.

What is the key advantage of semiconductor?

Unlike vacuum tubes, semiconductors are shock-proof. Moreover, they are smaller in size and occupy less space and consume less power. Compared to vacuum tubes, semiconductors are extremely sensitive to temperature and radiation. Semiconductors are cheaper than vacuum diodes and have an unlimited shelf life.

Why semiconductors are preferred in most of the applications?

Advantages of Semiconductor Devices Semiconductor devices require low voltage operation as compared to vacuum tubes. Owing to their small sizes, the circuits involving semiconductor devices are very compact. Semiconductor devices are shock proof. Semiconductor devices are cheaper as compared to vacuum tubes.

What are the different types of semiconductor materials?

Speaking in terms of electrical conductivity with units of Ω-1 cm-1, semiconductor materials are those with electrical conductivity between 10-9 Ω-1 cm-1 and 102 Ω-1 cm-1. Traditionally, group IV elements like Silicon (Si) and Germanium (Ge) are considered the Elemental Semiconductor Materials i.e. semiconductors with only single atom species.

Why are semiconductors so important to the electronics industry?

Over the last 70 years, semiconductors became a crucial element in the manufacturing of electronics. Since the invention of the Transistor, the world of electronics has always been on an exponential curve in terms of research, development, manufacturing, bringing up new devices and technologies.

How are semiconducting elements distributed on the periodic table?

Eleven types of semiconducting elements are distributed in the IIIA to IVA groups of the periodic table. C, P, Se have two forms of insulator and semiconductor; B, Si, Ge, Te have semiconductivity; Sn, As, Sb have two forms of semiconductor and metal.

What kind of semiconductor is used in a cell phone?

Different types of semiconductor (P or N) are produced depending on the element used, with boron being the most common type of P-type dopant. The micro-electrical components and wiring in the phone are composed mainly of copper, gold, and silver.
