Penn Researchers Discover New Method for Making Graphene Alternative

In a study published in the journal Nature Communications, a research team led by Professor of Physics and Astronomy Charlie Johnson revealed a new technique for making molybdenum disulfide, a potential graphene competitor. Graphene, a single-atom-thick lattice of carbon atoms, is often touted as a replacement for silicon in electronic devices due to its high conductivity and thinness. Molybdenum disulfide would be superior to graphene in that it is possible to turn its conductivity on and off, and it emits light, meaning it could be used in applications like LEDs, self-reporting sensors, and optoelectronics.
