The question is always this: keep going with the materials that I am currently growing, or dedicate time to trying new materials. Its an age-old dilemma of not wanting to start over vs not wanting to be stuck on a path that less productive. In the world of 2D materials, this dilemma takes the form of sticking to the tried-and-true family of TMDC's (MoS2, MoSe2, WS2, WSE2), or to journey out into the uncharted waters of TMDC's where the metal is not M or W. It also means journeying out into the really uncharted waters of 3-6 and 4-6 binary 2D materials, such as SnS and GeSe. The prospect of growing these materials in large scale is tantalizing, if nothing other than for the prospect of having a complete library of 2D materials accessible at the wafer scale. I give much thanks to Yuda Zhao, who presented on PtS2, as well as for several others who presented on materials such as SnS. As a grower, I see small-scale proof-of-concepts as an encouraging sign that large-scale growth could be fruitful. After seeing the world of 2D materials on display here at MRS, I am encouraged that we will soon have access to them at the large scale, enabling a great variety of 2D devices to be made in the future.
