What are Semiconductors?

Semiconductors are materials with electrical conductivity between that of a conductor (like copper) and an insulator (like glass). This unique property is derived from their atomic structure—typically made from silicon, which can be altered by adding impurities, a process known as doping. This manipulation allows manufacturers to precisely control the material's electrical properties, enabling the creation of electronic components that are foundational to all modern electronics, including those used in AI.

How Semiconductors Work

At the heart of a semiconductor's functionality is its ability to control the flow of electrical current. Semiconductors can be treated to create either a surplus of electrons (n-type) or a deficit (p-type), which are necessary for forming basic electronic components like transistors. When combined, these doped regions can create junctions that allow current to flow in one direction under certain conditions—this directional flow is essential for the binary switching necessary in digital electronics.
