Semiconductor might not be something you think about daily, but it is the backbone of nearly every piece of modern technology. From powering your smartphone to enabling cutting-edge AI, these tiny chips are everywhere. But their importance doesn’t stop at gadgets—they have a transformative impact on economies worldwide, reshaping industries and driving innovation.
What Are Semiconductors?
At its core, a semiconductor is a material that has conductivity between a conductor (like copper) and an insulator (like rubber). Materials like silicon and germanium are commonly used to create semiconductors.
There are two main types:
- Intrinsic Semiconductors: Made of pure materials.
- Extrinsic Semiconductors: Modified by adding impurities to improve performance.
How Do Semiconductors Work?
Semiconductors have unique properties that allow them to control electrical currents. Unlike conductors, they don’t let electricity flow freely, but they’re also not entirely restrictive like insulators. This balance enables their use in electronic circuits.
For instance, semiconductors can amplify signals, switch currents on and off, and store information—functions crucial for devices like computers and smartphones.
