a The XRD pattern of DAST NWs. b SEM image of a DAST NW from the [001] perspective, where, based on the typical characteristics of bulk crystal growth, the [-111], [111], [1-11], and [110] faces can be identified. c DAST molecular alignment in the NW, where the tosylate anions have been omitted for clarity. d The cross-section of a DAST NW cut by a focused ion beam. e AFM image of a DAST NW. e The surface roughness of a DAST NW, as determined using an AFM
