Bi2Te3bulks were synthesized by a simple high pressure and high temperature method to investigate the texture evolution and anisotropic thermoelectric properties. The multiple microstructures, defects and strains were revealed by HRTEM images. Pressure tuning resulted in increasing of electrical conductivity and thermopower, yielding a 10-fold improvement of power factor at 4 GPa, with respect to that at 0.5 GPa. The abnormally weak anisotropy of electrical resistivity was attributed to the inhibition of carrier mobility by roughness and strains along the layer surface.
