Major properties related to the VO2 1st order phase transition. (a) Reversible Monoclinic-Rutile crystallographic phase transition of VO2 at the vicinity of TMiT ~ 68 ºC, (b) The corresponding reversible electronic phase transition due to the reversible opening-closing of the d band orbital, (c) Ideal optical response of a VO2 based thermochromic coating; (1) TVIS > 50%), (2) TMIT ~ 25 °C) and primarily, a large modulation in the (NIR) & (IR) spectral range (∆TTRANS).
