Transition metal dichalcogenides — A new material class for semiconductor electronics?

Since three years we witness a continuously increasing interest of the electronic device community in the new material class of single/few-layer TMDs. The present paper introduces this type of materials, discusses the properties of TMDs relevant for electronic applications, and reviews the state-of-the-art of TMD transistors. Besides the achievements, problems of TMD transistors are discussed and the prospects of TMDs in electronics are examined.
