Image of FIG. 1.
FIG. 1.

Reduction in the photodegradation effect observed during HDT-SAM incubation. Applied laser power density: (a) 463, (b) 146, and (c) . Values are normalized to the initial condition.

FIG. 2.

Evolution of the PL peak intensity from the etched GaAs structure exposed to (a) 2 mM of HDT dissolved in degassed ethanol and (b) degassed ethanol. Values are normalized to the initial condition. The differential PL intensity in (a) and (b) is shown in (c).

Image of FIG. 3.
FIG. 3.

(a) FTIR peak absorbance and (b) position of the asymmetric C–H stretching mode of alkane in HDT-SAMs. Closed/open points represent separate data series. Error bars are estimated from baseline uncertainty. Inset: IR spectrum after stabilized formation (22 h) illustrating the asymmetric and symmetric C–H stretching modes, and the asymmetric stretching modes of .

Image of FIG. 4.
FIG. 4.

Peak PL intensity and IR absorbance with fitting results corresponding to Eqs. (2) and (3). Data are normalized to the respective saturation values of each curve.
