Contact Strategies for Transition Metal Dichalcogenides
As the continued need for compact and energy-efficient microelectronics continues alternative materials to silicon are required. One such alternative is the family of two-dimensional materials, such as transition metal dichalcogenides. These have attracted great attention due to their inert surfaces and thickness-dependent electrical and optical properties, with applications in flexible electronics, ultra-scaled field effect transistors, and spintronic devices. While substantial progress has been made in the basic understanding of these materials from their electrical and optical properties to their physical characteristics there remain a number of roadblocks to their integration into commercial devices. The CONTACT project will investigate two of the most prominent integration issues; 1) controllable doping of these materials, and 2) the reduction of contact resistance in the source/drain regions.
