Resume: In this study, we examd. individual bismuth telluride nanowires (NWs) electrodeposited in polycarbonate membranes (PCM) used as sacrificial templates. It has been demonstrated that the compn. of Bi2Te3 is controlled by the electrodeposition conditions, e.g. the applied potential. High-resoln. transmission electron microscopy (HRTEM) shows that the av. grain size of NWs increases with increasing Te content. Our results also reveal that the electrodeposited bismuth telluride NWs are n-type, and their elec. cond. increases with increasing Te content. These NWs also demonstrated a max. power factor of 195.8 mW/m·K2 for the Te-rich NW (d = 162 nm) at 300 K. [on SciFinder(R)]
