Crystal structure and epitaxial growth model. a Orthorhombic Sb2S3 consists of (Sb4S6)n ribbons stacked parallel to [001] direction. b Atomic configuration at the Sb2S3/TiO2 interface epitaxially grown between the (101) planes of orthorhombic Sb2S3 and anatase TiO2 crystals. c Schematic illustration of the OCE nucleation/growth model for the growth of Sb2S3 single-crystalline cuboids on polycrystalline TiO2 nanoparticle film, where the most competitive TiO2 nanoparticle orientation for the Sb2S3 single-crystals to nucleate/grow features its (101) plane tilting an angle (α) on substrate plane close to α = 33o (Particle 2), but the nucleation/growth at other sites around (e.g., particle 1 of α = 0o and Particle 3 of α = 62o) is relatively much slower or suppressed due to their unfavorable TiO2 (101) plane orientations
