Excerpt:
…..This week saw a somewhat different take on constructing these minuscule devices: chemistry. A research team linked up the two materials used in the earlier study, graphene and molybdenum disulfide, using a single bridging molecule that could react with each of them. The chemistry of the bridging molecule also influenced the behavior of a device made using this approach…..
…..The new work aims to create a single molecule that acts as a bridge between graphene and molybdenum disulfide. At one end of the bridge, there’s a chemical group that reacts with molybdenum disulfide. On the other, there’s a chemical group that interacts with graphene. In between is just a short, unreactive benzene ring.
Starting with some molybdenum disulfide flakes, the researchers ran a reaction that linked the bridge to the flake. Afterward, the flakes were placed in with graphene sheets, where the other end of the bridge molecule reacted with the graphene. The result was a graphene sheet decorated with molybdenum disulfide flakes, with the two connected via the bridge molecule…..
