What is a semiconductor used for?

Answer 1

Semiconductors may be used to fabricate electronic devices. This is done quite often.

Most of the electronic devices they're used for are called "transistors". Often, several

transistors are combined in a single small device, called an "integrated circuit".

A few examples of where these devices may be found in real life include . . . -- almost every radio in the world

-- almost every TV set in the world

-- almost every landline telephone in the world

-- every TV remote

-- every GPS

-- every CD/DVD player

-- every cellphone and every smartphone in the world.

Answer 2

Semiconductors are used to conduct electricity under some conditions but not under other conditions.

We use semiconductors to control the flow of electric current.

It is used like a resistor to slow down the current of electricity.
