Electrolyte Effect on Nanotubes Properties

The ability to electrodeposit magnetic (CoNiFeCu) and semiconductor (Bi2Te3) nanotubes was demonstrated from two different electrochemical systems. Electrodeposited multilayered CoNiFeCu/Cu nanotubes were fabricated by pulsing the applied potential. The electrolyte temperature affected the tube formation and the nanotubes giant magnetoresistance (GMR) saturation field. Both p/n-type Bi2Te3 alloy nanotubes were deposited under constant potential from different electrolyte concentrations and component ratios. We report the Seebeck coefficient measurement method for Bi2Te3 alloy nanotubes obtained by electrodeposition.
