 Solid state (electronics) - Wikipedia, the free encyclopedia
As the use of vacuum tubes in consumer electronics has decreased (an exception being the CRT still widely used for TV and desktop computer monitors), the term "solid state" has been increasingly used as a synonym for "no moving parts".
In electronics, solid state circuits are those that do not contain vacuum tubes.
Solid state means that electrons flow throughv solidsemiconductor, materials such as Germanium (Ge), Silicon (Si) etc, and not through empty spaces, such as in vacuum tubes.

 ROOT2 Limited - LOW NOISE SOLID STATE RELAY
Solid State relays certainly generate considerable levels of continuous R.F. noise and are also susceptible to electromagnetic disturbance from outside sources, therefore they fall within the requirements of the Regulation.
Many manufacturers will be surprised to learn that solid state relays will probably be the single most significant generator of RF noise within the whole of their apparatus: a typical SSR operating with a 30amp load produces a continuous noise output of over 120db at 150KHz, (the EN55022 limit is 65db).
The ROOT2 solid state relay has been fully tested and certified as EMC compliant while operating with a 240vac 80amp load - the immunity test involved the introduction of 1KV pulses at the low voltage control circuit and immersion in high power RF signals within a sealed chamber.

 Electronic and photonic behaviour (from nanotechnology) --  Encyclopædia Britannica
Electronics is the branch of physics concerned with the generation and behavior of electrons, as in transistors and electron tubes.
Electronics engineering is that branch of electrical engineering concerned with the uses of the electromagnetic spectrum and with the application of such electronic devices as integrated circuits, transistors, and vacuum tubes.
Semiconductor devices are grown with thin layers of differing composition so that electrons (or “holes” in the case of missing electron charges) can be confined in specific regions of the structure (known as quantum wells).

 RPI Center for Terahertz Research - THz Solid-State Electronics
Plasma wave electronics relies on propagation of surface plasma waves in the channel of a field effect transistor.
The terahertz range – which lies between the frequency ranges of electronic and photonic devices – is often referred to as the "terahertz gap" because of the lack of both high-power, low-cost, portable room temperature THz radiation sources and efficient detectors to collect and record those signals.
The upper frequency limit of transistors operating in conventional regimes is limited by the transit time of carriers under the gate, for a field effect transistor, or across the base and collector depletion region, for a bipolar junction transistor.
