Nearly commensurate to commensurate phase transition in 1 T-TaS2 and CDW suppression by oxidation in thin flakes. a TEM diffraction images of 1 T-TaS2 at 295 K (red, NC phase) and 100 K (blue, c phase). Weaker peaks are due to CDW distortion. b Resistivity vs. temperature of bulk 1 T-TaS2 crystal around the first-order, NC-C transition. Reprinted from Tsen et al. (2015) (Proc. Natl. Acad.
