Here we show that linear alkylamines n-C m H 2 m+1NH 2, with m = 4 through 11, are highly effective in protecting the optoelectronic properties of these materials, such as black phosphorus (BP) and transition-metal dichalcogenides (TMDs: WS 2, 1T'-MoTe 2, WTe 2, WSe 2, TaS 2, and NbSe 2). 14 Department of Nuclear Science and Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139 van der Waals materials have rich and unique functional properties, but many are susceptible to corrosion under ambient conditions.14 Department of Nuclear Science and Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139 PMC article.13 Department of Electrical Engineering and Computer Science, Massachusetts Institute of Technology, Cambridge, MA 02139.12 School of Physical Science, University of Chinese Academy of Sciences, 100049 Beijing, China.11 Center for Energy and Environmental Science, Shinshu University, 380-8553 Nagano, Japan.10 Department of Materials, University of Oxford, OX1 3PH, United Kingdom.9 Department of Chemistry, Massachusetts Institute of Technology, Cambridge, MA 02139.8 College of Information Science & Electronic Engineering, Zhejiang University, 310027 Hangzhou, China.7 Department of Materials Science and Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139.6 College of Materials Science and Engineering, Sichuan University, 610065 Chengdu, China.
