Fig. 1

a–c Optical images of the AgCN microwires grown on WS2 depending on the oxygen plasma treatment condition (pristine, 10 and 30 W). d–f SEM images of the AgCN microwires on WS2 depending on the oxygen treatment condition (pristine, 10 and 30 W). The red and orange arrows represent the molecular chain directions of AgCN aligned along the zigzag lattice of the substrate. g STEM image of the AgCN microwires grown on plasma-treated WS2 (30 W power). The red and orange arrows indicate the AgCN molecular chain directions. h Atomic model of the AgCN microwires grown on WS2. i Simulated SAED pattern of AgCN on WS2. j Experimental SAED pattern of AgCN grown on WS2. The diffraction signals of AgCN and WS2 are marked with black and red circles, respectively. k Histogram of the azimuthal distributions of the AgCN chain directions (red arrows) on pristine and plasma-treated WS2. l Density of the AgCN microwires grown on pristine and plasma-treated WS2. The error bars indicate the standard deviation from 10 to 15 samples. m Length distribution of the AgCN microwires grown on pristine and plasma-treated WS2. The inset shows the width distribution of the AgCN microwires.
