A Japanese university research team has found a material that could be used to make a low-price super disc with data storage capacity thousands of times greater than a DVD, the lead scientist said Monday. The material transforms from a black-colour metal state that conducts electricity into a brown semiconductor when hit by light, according to Shin-ichi Ohkoshi, chemistry professor at the University of Tokyo.The material, a new crystal form of titanium oxide, can switch back and forth between the metal and semiconductor states at room temperature when exposed to light, creating an effective on-off function.
