How many semiconductor devices are there?
Some examples of three-terminal semiconductor devices include Bipolar transistor, IGBT, Field-effect transistor, Silicon-controlled rectifier, TRIAC, Thyristor, etc.
What are the applications of semiconductors?
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.
Why are semiconductors special?
Because semiconductors have a unique atomic structure that allows their conductivity to be controlled by stimulation with electric currents, electromagnetic fields, or even light. Since electrons carry a negative charge, this type of crystal with extra electrons is known as an N-type or N-doped semiconductor.
What are the properties of semiconductors?
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.
Where are semiconductors used?
CPUs that operate personal computers are also made with semiconductors. Many digital consumer products in everyday life such as mobile phones / smartphones, digital cameras, televisions, washing machines, refrigerators and LED bulbs also use semiconductors.
Which is an example of DIAC?
Explanation: DIAC (Diode alternating current) is a 2 terminal device. It has got two zener diodes connected back to back which forms a DIAC (Diode alternating current). Explanation: NTE6408 is an example of DIAC.

What are the different types of semiconductor?
the best known are silicon (Si) and germanium (Ge).
What is the most common semiconductor material?
The most commonly used semiconductor material is Silicon. This is an element, it has 14 electrons, and its pure solid form melts at 1420 °C. Used for thousands of years to make ordinary glass, Silicon is a very common element.
Semiconductors are an ever-present element in modern technology. When judged by their ability to conduct electricity, these devices fall between full conductors and insulators. They are used as part of a digital circuit in computers, radios, telephones, and other equipment.
