What Are Semiconductors?
At their core, semiconductors are materials with electrical properties between those of conductors (like copper) and insulators (like rubber). Silicon, the most widely used semiconductor material, has unique properties that allow it to conduct electricity under certain conditions while resisting it under others. This dual behavior is the foundation of modern electronic devices.

How Do Semiconductors Work?
Semiconductors owe their functionality to a process called doping. By adding small amounts of impurities to pure silicon, scientists can control its electrical conductivity. There are two main types of semiconductors:
- n-type: Electrons carry the charge.
- p-type: The absence of electrons (or “holes”) carries the charge.
When these two types come together in a junction, they create a pathway that can either allow or block electrical current. This basic principle underpins the operation of diodes, transistors, and integrated circuits.
