"On the Beach Alone, at Night"
A composite of three scanning electron microscope images taken at different focal lengths of a silicon nanowire array synthesized via wet chemical etching of bulk silicon. The chemistry is "self-assembling" in that the silicon surrounding the nanowires is spontaneously etched under the right conditions. The images were captured using a NovelX mySEM low voltage scanning electron microscope. The near and far range images were taken with standard backscatter collection while the middle range image was taken using the Topo mode in order to capture the relief of the silicon "dunes." The three images were combined and colorized in Photoshop.
