    • The 20-nm Au films in the Elsayed-Ali study have a decay time that is shorter than that of the 80-nm films. This is not consistent with the trend from isolated colloid to bulk material.

    • Caution! Piranha solution is extraordinarily dangerous, reacting explosively with trace quantities of organics. It should be handled in very small quantities and with great care.

    • Presumably, as depicted in Figure 1, previously deposited colloids act as nucleation sites for additional growth and, hence, colloidal aggregates are formed.

    • There is a limit on the range of height measurements of these films with an AfM. These measurements can only be accurate while the film is still discontinuous so that a reference point of zero height exists.

    • The average film height was measured and used to quantify the colloidal film's growth and aggregation for a number of reasons. First, as noted, it is a representative and characteristic measure of the growth process and is consistent with other measures. Second, as discussed below, the growth in height is correlated to the measured intra- and inter-colloid dynamics. Finally, growth measured in terms of average film height allows for direct extrapolation to and comparison with the bulk, polycrystalline limit.

    • The analyzed time constants obtained with use of an exponential rise and exponential decay plus offset model were similar. However, as per the preceding discussion about the appropriate functional form for the time dependence of e-e scattering, it was felt that a more reliable analysis was to fit the decay function beginning after the e-e thermalization process is complete.

    • 4,55 and assuming a first-order rate equation, one would expect an electron transfer rate on the order of 100 fs. If the number of cross-linkers between adjacent colloids is taken into account, an even higher rate would be predicted. Thus, the rate of electron mobility is significantly faster than the e-ph coupling times reported herein, and it is reasonable to predict that electron dynamics within a given colloid are sensitive to the presence of adjacent colloids.
