Superlattices of prolate CdSe nanocrystals on silicon wafer

This field of cadmium selenide crystals is what scientists discovered when they aimed a scanning electron microscope on one of their experiments to look at the nanoscale level. The entire field of view is just 500 microns across—the size of a period at the end of a sentence. Studying formations at the nanoscale helps scientists discover new materials for technologies like computer memory and solar cells.
