Abstract
The invention provides flash-treated transparent conductive coatings based on indium tin oxide. Some embodiments provide a multiple-pane insulating glazing unit that includes two glass panes and a between-pane space. The two glass panes respectively define two opposed external pane surfaces. At least one of the two external pane surfaces has a flash-treated transparent conductive oxide coating.
