    • w value except for the 7 nm film curves, which were ±15% (higher uncertainty due to lower signal to noise ratio afforded by the thinnest film), and certainly could not explain the differences between thin and ultrathin films.

    • Extraneous effects associated with charge injection were a problem in certain samples near 110 °C. Only measurements in which these effects were absent or for which they could be accounted are presented.
