Abstract

Bi2Te3 assembled by disordered nanosheets with defects was prepared using a one-step easy synthesis strategy based on easy solvothermal synthesis routes. The high compatibile plane structure, minimization of nucleation and interfacial angle energies are the driving force of the crystal connection and the formation of the defects. To survey the impact of the defects on their thermoelectric properties, thermoelectric properties of bulk pellets have been investigated, and they exhibited preferable thermoelectric properties with a high ZT value of 0.68 due to its unique structural characteristics.
