Image of FIG. 1.
FIG. 1.

Unmodulated absorption spectrum (a, b), electroabsorption spectrum (c, d), and second derivative of the linear absorption (e, f) for devices based on (a, c, e) and (b, d, f) PbS nanocrystals. The insets show the transitions corresponding to first three peaks in the measured electroabsorption spectrum.

FIG. 2.

Change in absorption as a function of the square of applied voltage for the lowest three energy levels for (a) nanocrystal device and (b) nanocrystal device. A quadratic dependence of on is observed. The inset shows the device structure used for measurements.
