Transition metal dichalcogenides (TMD) are materials with the form MX2 where M is a metal and X can be Se, S, or Te. These materials have covalent bonding within the layers and Van der Waals bonding between the layers [1]. Unlike graphene, the existence of a band gap eliminates the need to form nanoribbons for two-dimensional crystal tunnel field-effect transistors (TFETs). Among TMDs, molybdenum...
As conventional transistors become smaller and thinner in the quest for higher performance, a number of hurdles are encountered. The discovery of electronic-grade 2-D crystals has added a new “layer” to the list of conventional semiconductors used for transistors. This paper discusses the properties of 2-D crystals by comparing them with their 3-D counterparts. Their suitability for electronic devices...
