Semiconductors

Front

What property of semiconductors changes with temperature?

Back

They conduct electricity better.

Front

What makes semiconductors super useful in electronic devices?

Back

Their unique ability to control electricity.

Front

What is the role of diodes in electronic devices?

Back

To only let electricity flow in one direction.

Front

How do transistors work in a flashlight?

Back

They let electricity flow to light up the bulb.

Front

What is the primary use of silicon in electronics?

Back

As a semiconductor material.

Front

Define a semiconductor.

Back

A material that has electrical conductivity between that of a conductor and an insulator.

Front

What is the difference between conductors and semiconductors?

Back

Conductors allow electricity to flow freely, while semiconductors can control the flow of electricity.

Front

What is doping in semiconductors?

Back

The process of adding impurities to a semiconductor to change its electrical properties.

Front

What are n-type semiconductors?

Back

Semiconductors that have been doped with elements that provide extra electrons.

Front

What are p-type semiconductors?

Back

Semiconductors that have been doped with elements that create 'holes' for electrons to move into.
