a Schematic illustration of type A nanostructure. TEM images of CdS-type A nanostructure lying flat b and standing c on the TEM grids. d Schematic illustration of type B nanostructure. e Dark-field STEM image of CdS-type B nanostructures. f Dark-field STEM image of a typical CdS-type B nanostructure standing on the TEM grid. Two bright strips, indicated by black arrows, can be clearly observed in the nanostructures. g Schematic illustration of type C nanostructure. h, i Dark-field STEM images of CdS-type C nanostructures.
