solid-state

Solid-state refers to electronic devices and components built using solid materials, primarily semiconductors like silicon, where electrical current flows through a structured, stable matrix. Unlike devices that rely on moving parts or liquids, solid-state technology offers greater durability, reliability, and faster operation. Examples include modern computers, smartphones, and hard drives. The term also describes the fundamental physical state of matter—solids—characterized by fixed, closely packed particles, which gives solid-state devices their stable and consistent properties essential for precise electronic functions.
