Tectonic arrangement of Bi2S3nanocrystals into 2D networks

Abstract

Two-dimensional Bi₂S₃ networks have been fabricated through a soft chemical route, which is first developed for fabrication of chalcogenide 2D networks without the assistance of any templates or catalysts. The aspect ratio of Bi₂S₃nanorods in the 2D networks can be kinetically controlled and tuned by adjusting the experimental parameters, which offers promise for extending their applications in nanoelectronic and optoelectronic devices. Experimental investigation of their assembly behavior suggests that either the oriented attachment or natural growth along a special crystallographic plane is of importance for the tectonic arrangement of Bi₂S₃nanorods into 2D networks.
