“…Important dopants include Fe and Ni (substituted for Co) and Sn and Te (substituted for Sb). 3,[5][6][7][8][9][10][11][12][13][14][15][16] Thin films of CoSb 3 have been prepared by different techniques including pulsed laser deposition 12 and dc magnetron sputtering. 17 Although most studies on skutterudites have been focused on the effects of rattler and dopant concentrations on thermoelectric properties, only recent work concentrated on lowdimension skutterudites such as thin films and nanowires.…”

Co-Sb thin films and nanowires were grown on gold-coated polymer templates by electrochemical deposition under different potentiostatic conditions from -0.8 to -1.0 V vs Ag/AgCl. The growth of nanowires was 3D and went through several growth stages starting from the gold-coated wall. Overgrowth of nanowires out of the porous template did not produce a fully dense film; instead, Sb-rich columnar structures (mushroom caps) were developed and connected by Co-rich needle-like structures. Compared to nanowires, the mushroom caps had a lower content of Co. With a more negative deposition potential, the content of Co in the nanowires and the mushroom caps increased. A composition of Co:Sb ) 1:3 in nanowires was obtained at a constant deposition potential of -0.965 V.

“…The ZT values for both the samples firstly increase and then decrease with increasing temperature. At about 550 K, Fe 0.6 Co 3.4 Sb 12 sample obtains the maximal ZT value (0.09), which is larger than the result of Kim (about 0.05) [19], however, unfortunately smaller than that of undoped CoSb 3 (0.17). It is related to the large electrical resistivity for Fe 0.6 Co 3.4 Sb 12 compound.…”

“…However, in the second method the Seebeck coefficient changes to positive approximately at 540 K. The reason is that the hole mobility is much larger than the electron mobility in the temperature range higher than 540 K [12], at which intrinsic excitation commences. It has been reported that the intrinsic CoSb3 shows the p-type conductivity [13,14]. In this study, the low purity of Co (99.8%) may be the reason for the appearance of n-type conductivity initially [15].…”

Thermoelectric materials may be used in devices as thermoelectric "air conditioner" in a smart house for improved energy efficiency. Energy harvesting uses ambient energy to generate electricity. It provides potentially low-cost, maintenance-free, long-life equipment by reducing the need for batteries or power chords. Energy harvesting (EH) is also known as power harvesting or energy scavenging. EH is considered to give benefits related to environmental friendliness, safety, security, convenience and affordability. EH can be used for brand enhancing. Technically, it can be used to make new things possible depending on visionary engineering. The variety of thermoelectric (TE) materials that can be used in energy harvesting is quite large, and the optimal material for a given application depends mainly on the temperature range in which the material is to be used. In this work we study the development and characterization of thermoelectric materials which were prepared by two different method, which were: a) ball-milling followed by sintering and b) ball-milling, microwave synthesis, high energy planetary ball milling, and sintering. Finally, we study the thermoelectric properties, calculate the band gaps and the ZT for the thermoelectric materials.
