Caption

The aluminum substrate shown at top rear is patterned with pores seeded with anodized gold, spaced at intervals of about half a micron (millionth of a meter). At middle rear, the single-crystal cadmium sulfide nanopillars are about 200 nanometers in diameter (billionths of a meter). The test device in the foreground is shown next to a dime for scale.
