Unique ZnO/ZnS nanocables were synthesized by the catalyst-free simple thermal vapor transport method. Using the high-resolution transmission electron microscopy, the interface and defect structures of nanocables were investigated. The nanocables were composed of two discrete structures, which grow along [0 0 0 2] or [0 1¯ 1 0] directions in wurtzite and [2 0 0] direction in sphalerite structures. Two-dimensional Moiré fringes appeared in the core area due to a different interplanar spacing between ZnO and ZnS. In the nanocables grown along [0 0 0 2] and [0 1¯ 1 0] direction, stacking faults, which lie in (0 0 0 2) and (0 1¯ 1 0) planes were observed likewise the identical defects were also found in the (1 1 1) plane of the sphalerite structure.This work includes an in-depth discussion regarding the structure and the growth of ZnO/ZnS nanocables.
