    In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flows in two forms: as negatively charged electrons, and as positively charged electron deficiencies called holes. In some semiconductors, the current consists mostly of electrons; in other semiconductors, it consists mostly of holes. Both the electron and the hole are called charge carriers. An example of a non-solid-state component is a cathode-ray tube (CRT). In this device, electrons flow freely through a vacuum from an electron gun, through deflecting and focusing fields, and finally to a phosphorescent screen. For data storage, solid-state devices are much faster and more reliable than mechanical disks and tapes, but are more expensive. Although solid state costs continually drop, disks, tapes and optical disks also continue to improve their cost/performance ratio. The first solid-state device was the "cat's whisker" detector, first used in 1930s radio receivers. A whisker-like wire was moved around on a solid crystal in order to detect a radio signal.[1][2]

    Electronics Dictionary: solid state

    Pertaining to circuits where signals pass through solid semiconductor material such as transistors and diodes as "opposed" to vacuum tubes where signals pass through a vacuum.

    Dictionary: solid-state

    Based on or consisting chiefly or exclusively of semiconducting materials, components, and related devices.

    WordNet: solid-state

    Meaning #1: characteristic of or relating to the physical properties of solid materials especially electromagnetic or thermodynamic or structural properties of crystalline solids

    Meaning #2: (electronics) consisting of semiconductor materials and components and related devices

    In electronics:

    Solid state (electronics) are circuits that do not contain vacuum tubes or, more currently, moving parts.

    Solid state relay is an electronic switch that contains no moving parts.

    Solid state disk, data storage device components that uses memory chips, such as SDRAMs, to store data.

    It means there are no moving mechanical parts like relays etc. All switching is done with transistors.

    Originally it meant no vacuum tubes. Don't knows what it means now?
