“…TSLs have been reported for various material systems including GaAs, GaP, , InP, − InAs, − ZnTe, ZnSe, ZnS, ZnO, SiC, , Zn 2 SnO 4 , and Zn 3 P 2 . ,− Tetragonal Zn 3 P 2 is a crystalline system with and has a pseudo-face-centered cubic symmetry (Figure S1 in the Supporting Information). , For instance, when a transformation matrix is used, the [100] and [101] directions in the tetragonal system correspond to the [110] and [111] directions in the pseudocubic system, respectively. Zn 3 P 2 has an indirect band gap of 1.315 eV, and also, it has a direct band gap of 1.49 eV at room temperature .…”

Zn 3 P 2 twinning superlattice nanowires with diameters of 100−300 nm were grown under Sn catalysis on fluorine-doped tin oxide glass by physical vapor transport. The nanowires grew along the [101] direction with nonparallel {101} side facets. The Zn 3 P 2 twinning superlattices had no noticeable crystallographic defects except periodic twin defects. A nonlinear relationship between the twin plane spacing and nanowire diameter was observed. The twin plane formation energy (4.0 × 10 −2 to 4.3 × 10 −2 J/m 2 ) was estimated by fitting the relationship from the nucleation model with a hexagonal nucleus with monolayer height at the triple-phase boundary. The unexpected nonlinear behavior despite the relatively high twin plane formation energy was ascribed to the strong interaction of P atoms dissolved in Sn droplets with the growth interface. P atoms in the droplets may have acted as a surfactant to reduce the liquid−solid surface energy.

“…(15) Calculations predicted that a constant spacing between the rotational twins would induce a direct bandgap in normally indirect bandgap semiconductors, such as group IV (Si, Ge) and III-V (GaAs) materials. (31,32) Zn 3 P 2 NWs (including twinned NWs), nanobelts (NBs), and nanotubes were usually synthesized using vapor phase transport, and their electronic and optoelectronic properties were also indentified. In many semiconductor and noble metal NWs with a cubic structure (e.g., GaP, InP, InAs, GaAs, ZnS, ZnS, ZnTe, Si, SiC, B 4 C, Cr 2 O 3 , Zn 2 SnO 4 , Zn 2 TiO 4 , Ag, Au), (111) twin planes are commonly found.…”

Electron tomography and high-resolution transmission electron microscopy were used to characterize the unique 3-dimensional (3D) structures of twinned Zn 3 P 2 (tetragonal) and InAs (zinc blende) nanowires synthesized by the vapor transport method. The Zn 3 P 2 nanowires adopt a unique superlattice structure that consists of twinned octahedral slice segments having alternating orientations along the axial [111] direction of a pseudocubic unit cell. The apices of the octahedral slice segment are indexed as six equivalent <112> directions at the [111] zone axis. At each 30 degrees turn, the straight and zigzagged morphologies appear repeatedly at the <112> and <011> zone axes, respectively. The 3D structure of the twinned Zn 3 P 2 nanowires is virtually the same as that of the twinned InAs nanowires. In addition, we analyzed the 3D structure of zigzagged CdO (rock salt) nanowires and found that they include hexahedral segments, whose six apices are matched to the <011> directions, linked along the [111] axial direction. We also analyzed the unique 3D structure of rutile TiO 2 (tetragonal) nanobelts; at each 90 degree turn, the straight morphology appears repeatedly, while the in-between twisted form appears at the [011] zone axis. We suggest that the TiO 2 nanobelts consist of twinned octahedral slices whose six apices are indexed by the <011>/<001> directions with the axial [010] direction.

“…31 Zn 3 P 2 belongs to a unique tetragonal system, whose lattice constant, c/a, ratio (1.414) leads to its having a pseudo face-centered cubic (fcc) symmetry. 32,33 Zn 3 P 2 NWs (including twinned NWs), nanobelts (NBs), and nanotubes were usually synthesized using vapor phase transport, and their electronic and optoelectronic properties were also indentified. 12c,34-36 The present work demonstrates that tetragonal Zn 3 P 2 NWs have virtually the same twinned superlattice structure as that of ZB InAs NWs.…”
