In this lesson, students search for transistor-based devices at school. They use the results of their search to explain the significance of the transistor in their lives. A transistor is a tiny device ...

In the same way that a pillow filled with pebbles is harder to get smooth than one stuffed with sand, chip makers are finding it harder to make transistors behave predictably as they shrink. Here, the ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has ...
