The AKAFUJI, or "Mt. Fuji in Red", is actually crystallized tungsten oxide (2/10,000 mm in size) photographed with a transmission electron microscope. The crystal was formed and developed by heating tungsten in a very low oxygen pressure. A series of steps can be observed along the slope with each step measuring about 2/10 millionths of a millimeter representing the layer of atoms. The study of crystal formation is a significant work which is one of the basic technologies for semiconductor industry but also for material sciences.
