23. Fractional SAM coverages were determined by ratioing the ellipsometric thickness for a partial monolayer to the thickness for a freshly prepared SAM on the same substrate. Coverages of 1 were obtained by ratioing the integrated F(1s) intensity for a partial SAM to its value for a freshly prepared SAM of 1 on that substrate.
24. We did not examine higher temperatures, as the rates of desorption were too fast to assume that the substrates achieved the desired temperature.
