Separating Solid-State Chemistry from Materials Chemistry[edit]

Just as a matter of clarity - when chemists refer to "Solid-State Chemistry", it usually refers to work on inorganic solids, independent of any useful properties they may have, while Materials Chemistry refers to work on any solid, organic or inorganic, with useful properties, and is more properly considered a (broad) subdiscipline between chemsitry (a basic science) and materials science (an engineering discipline). This distinction, of course, forces us to draw a distinction at a fuzzy point on things like MOFs/Coordination Polymers, but it's probably for the best that we draw it. — Preceding unsigned comment added by 24.3.171.128 (talk) 05:14, 26 November 2011 (UTC)

Solid State does not require that solid phases are used or exclusively used[edit]

The term 'solid state' in the 20th century arose when vacuum tubes were phased out by transistors. The vacuum tubes contained only matter in the solid phase. However, they were composed of many individual parts, surrounded by a vacuum space, enclosed in glass. A transistor, in contrast, is basically one individual working component, other than the wires / electrical leads and any housing. The semiconductor portion of n-type and p-type silicon (etc.) is one joined unit. THIS is the difference between solid state and non-solid state. Solid state technology has nothing to do with solid phases, gas phases, or liquid phases. A hypothetical liquid semiconductor, contained within some housing, would still be considered solid state. However, vacuum tubes are not solid state because they are composed of many discrete parts (made from various materials) in a three- dimensional architecture; they are not one single 'solid' piece of material doing the same function. — Preceding unsigned comment added by 97.121.231.220 (talk) 19:15, 24 October 2012 (UTC)
