Contour maps of an FTO thin film on a PET substrate for bubbler pressure variations. The bubbler pressures were varied at (a) 40.2 Torr, (b) 43.2 Torr, (c) 45.7 Torr, (d) 55 Torr, (e) 60.2 Torr. (f) The sheet resistance uniformity and figure of merit of the FTO thin film under bubbler pressure variations.
