Wang, materials scientist Manish Chhowalla, and their colleagues report a way to quickly create metal electrodes on a single layer of molybdenum disulfide using a standard laboratory electron-beam evaporator. The researchers first grow single-layer molybdenum disulfide on a silicon substrate. They place the sample in the evaporator and coat it with a 10-nm layer of indium followed by a 100-nm gold layer.

It’s common for molybdenum disulfide, for example, to be missing sulfur atoms. When the electric field is applied, atoms from the metal electrodes may move into the vacancies, creating a bridge that allows current to flow directly between the two electrodes and changing the material’s resistance, Akinwande says.
