Fullerene switch. An artist’s rendering of a fullerene switch with incoming electron and incident red laser light pulses. ?2023 Yanagisawa et al. For the first time, an international team of researchers, including those from the University of Tokyo’s Institute for Solid State Physics, has demonstrated a switch, analogous to a transistor, made from a single molecule called fullerene. By using a carefully tuned laser pulse, the researchers are able to use fullerene to switch the path of ...
