Modern computer chips contain billions of silicon transistors, but silicon is nearing the limits of how small and powerful it can become. To keep improving electronics, scientists are investigating ultrathin materials that could work alongside silicon in future transistors.
One of the most promising options is molybdenum disulfide, a member of a family of atomically thin materials known as transition metal dichalcogenides (TMD). This material is only three atoms thick, consisting of a layer of molybdenum between two layers of sulfur.
