Abstract

Abstract : Assembly and fabrication of high‐quality heterostructures with desirable compositions and sequences is a great challenge. In this work, with the assistance of supercritical CO2 (SC CO2 ), we successfully prepared complex heterostructures of WS2 ‐WO3 ⋅H2 O/1T‐2H MoS2 in selective stacking assembly. Thanks to the unique properties of SC CO2, it can help to construct a unique solvent system where the hydrophilic or hydrophobic structure for the 2D layer heterostructure can be chosen. Then 2H‐WS2 /2H‐MoS2, as the preferred van der Waals heterojunctions, are formed efficiently. More information can be found in the Communication by Q. Xu, Y. Jia et al. onpage 632 in Issue 9, 2017 (DOI:10.1002/cnma.201700058 ).
