As an interesting morphology and phase, the 1D bicrystalline (twinned) nanostructures have received much consideration because of their peculiar structure. In this paper, bicrystal nanobelts of Zn3P2 and Cd3P2 have been prepared on a large scale, via a simple vapor-solid process. The products were characterized using X-ray diffraction. scanning electron microscopy, transmission electron microscopy, as well as energy-dispersive X-ray spectrometer and the results revealed that both of them are of bicrystal shapes with the preferred growth axis along the [101] directions. P-type Field-effect transistors (FETs) based on single Zn3P2 and Cd3P2 nanobelts were fabricated, which revealed the thermal activation of carriers as the dominant transport mechanism, as was verified under the measurements at various temperatures (100-300 K).
