Abstract

In this study, we examined individual bismuth telluride nanowires (NWs) electrodeposited in polycarbonate membranes (PCM) used as sacrificial templates. It has been demonstrated that the composition of Bi₂Te₃ is controlled by the electrodeposition conditions, e.g. the applied potential. High-resolution transmission electron microscopy (HRTEM) shows that the average grain size of NWs increases with increasing Te content. Our results also reveal that the electrodeposited bismuth telluride NWs are n-type, and their electrical conductivity increases with increasing Te content. These NWs also demonstrated a maximum power factor of 195.8 mW/m·K² for the Te-rich NW (d = 162 nm) at 300 K.
