Understanding the Basics of Semiconductors and Their Applications

Semiconductors are materials with electrical conductivity between conductors (like copper) and insulators (like glass). They are called “semiconductors” because they can conduct electricity under certain conditions but not under others.

Understanding the Basics of Semiconductors:

Semiconductors play a crucial role in modern technology and are essential components in many electronic devices we use every day. Here are some of the key roles that semiconductors play.

The Role of Semiconductors:

Semiconductors are used to make transistors, which are tiny electronic switches that can control the flow of electrical current.
