Talk:Metal–insulator transition

Can we clarify

 * Are the M-I transitions always 'sharp' phase transitions between different crystal structures ?
 * When pressure causes the transition, is the metallic phase always the high pressure form ?
 * When temperature causes the transition, is the high temperature form always the metallic state ? - Rod57 (talk) 11:23, 21 March 2020 (UTC)

The review by Imada, et al. is cited here and is so comprehensive, the structure of this page would naturally flow from it. Mechanisms followed by examples... BaconEggonomics (talk) 16:51, 4 February 2021 (UTC)
