resistivity of intrinsic semiconductors decreases exponentially with temperature; does that mean any insulator becomes a semiconductor if it survives to a high enough temperature? #physics #band-structure
the Fermi level is what needs to be in a conduction band to get a metal or near two of them to get a semiconductor #physics #band-structure
“A "Mott transition" is a metal-nonmetal transition in condensed matter. Due to electric field screening the potential energy becomes much more sharply (exponentially) peaked around the equilibrium position of the atom and electrons become localized and can no longer conduct a current.” A sudden transition, which can be provoked by temperature, pressure, or doping. #physics #band-structure

“In addition, all insulators become conductors at very high temperatures as the thermal energy of the valence electrons is sufficient to put them in the conduction band.” metals? or semiconductors? or first semiconductors, then metals? or just plasma? #band-structure #physics

how to calculate Pourbaix diagrams
#security Russ Cox says: “For the record, back in 2013, Ken told me that the backdoored compiler did in fact exist and was deployed, but it had a subtle bug that exposed the backdoor: the reproduction code added an extra \0 to the string each time it copied itself. This made the compiler binary grow by one byte every time it rebuilt itself. Eventually someone noticed and debugged what was going on, aided by the fact that the “print assembly” compilation mode did not insert the backdoor at all, and all traces were cleaned away. Or so we believe.”
