What is semiconductor explain?
What is a semiconductor? Semiconductors. Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.
What are some examples of semiconductors?
Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “metalloid staircase” on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others.
What are uses of semiconductor?
Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits. Such devices have found wide application because of their compactness, reliability, power efficiency, and low cost.
What are the electrical and physical properties of a semiconductor?
At absolute zero, semiconductors are perfect insulators, The density of electrons in conduction band at room temperature is not as high as in metals, thus cannot conduct current as good as metal. The electrical conductivity of semiconductor is not as high as metal but also not as poor as electrical insulator.
What is intrinsic and extrinsic semiconductor?
Intrinsic semiconductors are solely reliant on temperature while Extrinsic semiconductors are affected by temperature and the number of contaminants present. Intrinsic semiconductors are not further classified while N-type and p-type semiconductors are two types of semiconductors in Extrinsic semiconductors.
What are the 3 types of semiconductor?
In simple words, Semiconductor devices are a type of electronic components that designed, developed and manufactured based on the Semiconductor materials like Silicon (Si), Germanium (Ge) and Gallium Arsenide (GaAs).
What is a semiconductor product?
A semiconductor product is the final or intermediate form of an incorporated circuit in a chip. It has an electronic function. The topography is the design of the layout, that is, the three-dimensional location of elements and interconnections of an integrated circuit.
Where are semiconductors most used?
Semiconductors are used in almost every sector of electronics. Consumer electronics: Mobile phones, laptops, games consoles, microwaves and refrigerators all operate with the use of semiconductor components such as integrated chips, diodes and transistors.

What is the use of a semiconductor?
Semiconductors are an essential component of electronic devices, enabling advances in communications, computing, healthcare, military systems, transportation, clean energy, and countless other applications.
What are p and n-type semiconductors?
The majority carriers in a p-type semiconductor are holes. In an n-type semiconductor, pentavalent impurity from the V group is added to the pure semiconductor. Examples of pentavalent impurities are Arsenic, Antimony, Bismuth etc. The pentavalent impurities provide extra electrons and are termed as donor atoms.
What is called intrinsic semiconductor?
What are Intrinsic Semiconductors? Semiconductors that are chemically pure, in other words, free from impurities are termed as intrinsic semiconductors. The number of holes and electrons is therefore determined by the properties of the material itself instead of the impurities.
What is meant by extrinsic semiconductor?
Extrinsic semiconductors are semiconductors that are doped with specific impurities. The impurity modifies the electrical properties of the semiconductor and makes it more suitable for electronic devices such as diodes and transistors.
