Semiconductor

A semiconductor is a tiny material used inside electronics that helps control the flow of electricity.

Think of it like a traffic cop for electricity. It can let electrical signals pass or stop them depending on what the device needs.

String millions of those tiny stop-and-go switches together and you get a computer chip, the part that makes your gadget actually work. Semiconductors are the brains inside your phone, TV, car, and even your hearing aids.

The most common semiconductor material is silicon, which is why you hear the phrase “Silicon Valley.”

Bottom line: semiconductors are the tiny electronic building blocks that help your devices think, remember, connect, and run.
