However, several processing challenges related to organic contamination at the interfaces of the 2D material and the gate oxide must be overcome to realize robust devices with high yield. Here, we demonstrate an optimized process to realize high-performance field-effect transistor (FET) arrays from large-area (~5000 um2) monolayer MoS2 with a yield of 85 %. A central element of this process is an exposed material forming gas anneal ","authors_text":"Arvind Balijepalli, Brent A. Sperling, Curt A. Richter, Jeffery B. Klauda, Nicholas B.
