Bi2Te3 has an extensive application as thermoelectric materials. Here, large scale single-crystal hexagonal nanoplates(NPs) with size of 0.4–0.8 μm were synthesized successfully by hydro-thermal method. X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission (TEM) used to characterize the nanoplates, which confirm single crystal quality smooth surface morphology size. We d...
