Beschreibung:
  • This chapter presents a summary on the electrodeposition of Bi2Te3- and Sb2Te3-based thin films and nanowires for room temperature applications. The depositions are performed in a conventional electrochemical cell setup with the desired substrate as cathode, platinum wire as anode, and an Ag/AgCl reference electrode, controlled by computer-aided potentiostats. An improved thermoelectric performance can be achieved with ternary Bi2Te3-based thin films. As the process of electrodeposition is not restricted to flat substrates, the method can be easily adopted to synthesize nanowires, if the deposition surface, that is, the working electrode, is constrained by a suitable nonconduction template. Two types of porous membranes are commonly used for this purpose: track-etch membranes produced by ion irradiation of polycarbonate films and subsequent wet-chemical etching, and porous anodic alumina (PAA) membranes based on an electrochemical oxidation process. The chapter focuses on the latter, as they provide ordered pores with a high density.
