Answer the following:

Why do some materials conduct electricity/current, why do some materials insulate from electricity/current, and why do some materials semi-conduct electricity/current?

What you believe to be the most amazing use of semi-conductor technology (this could include mini, micro, and nanotechnology) in use today, or being developed for future uses. List the Internet, and other resources.

SOLUTION

Semiconductor materials are materials that have electrical conductivity between that of a conductor and an insulator. They are used in a wide range of electronic devices such as transistors, solar cells, and diodes. The most commonly used semiconductor material is silicon, but other materials such as germanium and gallium arsenide are also used. The electrical properties of a semiconductor can be modified by introducing impurities, a process known as doping, which is used to create different types of semiconductors such as p-type and n-type semiconductors.
