Effect of Lanthanum Doping on Modulating Thermochromic Properties of VO2 Thin Films
Lanthanum (La) doped vanadium dioxide (VO2) thin films were fabricated through a facile sol-gel technique. The La doping was found to be effective in reducing the phase transition temperature (τc) of VO2 below the 4 at.% doping level, with a reducing rate of -1.1 °C/at.%. In addition, below the 3 at...
