Abstract
A layer of indium is deposited as small islands on a photosensitive material. The islands and the material not covered by the islands are bombarded with ions to cause sputtering of the islands and the material. When the islands have been sputtered away, the material has a surface consisting of cones and pyramids. Such a surface is more efficient at absorbing photons than is a smooth surface.
