Semiconductors are at the heart of most electronics. We explain what semiconductors are, how they work, and just how tiny those transistors can get.

A semiconductor has conductivity between a conductor and an insulator, allowing precise control of electrical current. Learn how they work and why they’re essential in modern electronics.

But how do solar panels work? Here is what you need to about solar energy and photovoltaic, or PV, technology. What is solar energy? Solar energy is energy that comes from the sun.

Semiconductor chips are electronic devices that store and process information. Today they can contain billions of microscopic switches on a chip smaller than a fingernail.

3. How do you build a semiconductor chip? The starting point for the vast majority of semiconductors is a thin slice of silicon called a wafer.

What is a semiconductor? An electrical engineer explains how these critical components work and are made From the 10 insights on today's news that will make you smarter tomorrow series ...

How Do Semiconductors Work? When voltage is applied across a material such as a semiconductor, the negative side of the voltage pushes electrons (since like charges repel), and the positive side ...
