Solid-state (adjective)

1. Of or relating to electronic devices and systems that use semiconductors and solid materials rather than vacuum tubes or mechanical devices.
2. Of or relating to solid-state physics, the study of the properties of matter in a solid state.

Origin:

Coined in 1947 by william shockley, walter houser brattain, and john bardeen, american engineers and physicists who together developed the first practical point-contact transistor, at bell labs.

Examples:

1. Solid-state electronics are more reliable than vacuum tube electronics.
2. The solid-state drive is faster than the hard drive.
3. The solid-state physics is the branch of physics that studies the properties of matter in a solid state.
4. This solid-state amplifier is more efficient than its tube-based counterpart.
5. Solid-state technology has replaced many of the mechanical devices in modern appliances.
