Gao doi:10.1038/nmat4915 PtSe2 and CuSe monolayers obtained by selenization of a metal substrate are shown to intrinsically form periodic patterns by varying the amount of Se atoms deposited. These patterns are used for the localized absorption of molecules and nanoclusters.

Knüsel, Stephan J. P. Kress, Ferry Prins, Steven C. Erwin and David J. Norris doi:10.1038/nmat4889 Quasi-two-dimensional CdSe nanoplatelets are shown to grow in concentrated solvent-free melts, without mixed surfactants.
