Tectonic arrangement of Bi2S3 nanocrystals into 2D networks

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 Bi2S3 nanorods 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 Bi2S3 nanorods into 2D networks.
