Abstract

The principal aim of this equipment proposal is to acquire a commercial system that would allow us to grow 2D semiconductors such as MoS2 and related semiconducting transition metal dichalcogenides (TMDCs: MoS2, MoSe2, WSe2, WS2) on the wafer scale (4”) and with high quality and reproducibility. These materials have a unique combination of atomic scale thickness, di-rect band gap, strong spin-orbit coupling and favorable electronic and mechanical properties that make them interesting for applications and fundamental research in high-end electronics, DNA sequencing and personalized medicine, spintronics, optoelectronics, energy harvesting, flexible electronics. EPFL has a leading role in the research in 2D TMDC semiconductors which started with the demonstration of the first transistor based on MoS2 in 2011 [Radisavljevic11a]. The related research field was recently ranked among top 10 in physics by Thomson Reuters (http://goo.gl/hpDWXp). The market for systems for growing large-area 2D TMDCs has reached maturity and several manufacturers are now offering turn-key ready solutions. An installation of such a system at EPFL will help maintain our global edge in 2D materials-related research, allow us to more rapidly pursue research in this direction and would also be key for its possible commercialization.
