Roll 'em up, move 'em out: The growth of SnS2 and SnS2/SnS nanotubes and nanoscrolls with ordered superstructures is promoted by the relaxation of stress between adjacent SnS2 and SnS layers. Partial decomposition of the SnS2 precursor to more sulfur-deficient SnS was manifested in the exfoliation of layers and scrolling. The presence of the two main structures (see picture) was confirmed by HRTEM and Raman spectroscopy.
