2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/151879We draw attention to the past literature on valley phase transition in Si(100) MOSFETs. The recent experiments performed by Kravchenko and co-workers indicating metal-insulator transition in Si MOSFETs are also in accord with the valley phase transition mechanism.1 page, in REVTEX, no figuresStrongly Correlated Electronstext
