Fabrication of thermoelectric materials with bismuth nanowire array

It has been theoretically verified that the thermoelectric performance can be improved greatly when normal thermoelectric materials possess low dimensional structure. In our lab., Doped N-type and P-type Bi nanowire array thermoelectric materials have been fabricated by electrodeposition technology. The porous alumina films with nano-pore array structure were used as template, and one-dimensional thermoelectric materials dispersed in alumina matrix have been obtained, and their composition and structure have been analyzed.
