Calculators are amazing devices used for quick calculations.
They use semiconductors in two places:
-- in chips (widely known)
-- in display
An Integrated Chip, which performs calculations, employs transistors, FETs, diodes, etc. These are made up of semiconductors. The IC is the brain of the calculator.
Next, the important part is display which used Liquid Crystal Display. In modern day calculators, Twisted Nematic crystal display is used where voltage changes must be made to increase or decrease the amount of light passing through them to create numbers. Instead of using different plates for the 7 segments and supplying separate voltage for each of them, a single plate is used and semiconductor in the form of FETs is embedded in glass so that voltage of every segment can be controlled by the semiconductor device and a common voltage source can be used. Nowadays, calculators form characters other than numbers which requires only a selected area to be supplied with voltage. This is accomplished using semiconductors.
Germenium and silicon are the examples of Semiconductors.
Minority carriers are charge carriers in a semiconductor that are present in smaller quantities compared to majority carriers. In n-type semiconductors, minority carriers are holes, while in p-type semiconductors, they are electrons. These carriers play a crucial role in determining the electrical properties of semiconductors, particularly in processes like recombination and conduction. Their behavior is essential for the operation of devices such as diodes and transistors.
Commonly doped silicon is used to make semiconductors, but advancements in organic electronics now mean that semiconductors can be made from molecules made from elements such as carbon, hydrogen, oxygen, sulphur, nitrogen and a few others.
Those semiconductors in which some impurity atoms are embedded are known as extrinsic semiconductors.
