Preparation and thermoelectric properties of annealed CoSb and CoSb 2 thin films deposited through RF co-sputtering

Metal-arene reduced Fe–Sb nanoparticles as a highly efficient catalyst for nitrophenol reduction

“…Within the intermetallic class, transition metal based binary and ternary antimonides have shown remarkable properties in the context of their applications in thermoelectrics, lithium/sodium ion batteries, electrochemical performance etc. [1][2][3][4][5][6] Binary antimonides, and FeSb in particular, have been observed to show enhanced catalytic and electrochemical performance as compared to their constituent elements. [7][8][9] Recently, FeSb nanoparticles embedded in nitrogen-doped carbon layers were shown to exhibit excellent activity and stability to the ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) in alkaline medium.…”

An enhanced power factor via multilayer growth of Ag-doped skutterudite CoSb3 thin films

“…20 Therefore, many studies on the synthesis of high performance thin films, including CoSb 3 films, have been investigated. [21][22][23][24][25][26] For example, A. Ahmed et al 27 obtained a power factor of 7.92 mW m K −2 for the CoSb 2 -containing mixed phase thin film and 1.26 mW m K −2 for the stoichiometric CoSb 3 thin film. However, TE properties of CoSb 3 thin films remain lower than those of bulk materials due to the difficulty of controlling precisely the composition of the thin films.…”

Fabrication, micro-structure characteristics and transport properties of co-evaporated thin films of Bi2Te3 on AlN coated stainless steel foils

“…The microstructure, composition, crystal structure and orientation of the thin films were evaluated by high resolution field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD), respectively. The details of the characterization methods have been published elsewhere 7 , 12 .…”

“…Recently, attempts have been made to improve the thermoelectric efficiency of materials based on approaches such as carrier concentration optimization using impurities 6 – 8 , band structure modifications 8 , and lattice thermal conductivity reduction 3 , 9 . ZT values can be significantly improved in low-dimensional materials due to the stronger influence of quantum confinement effects and phonon scattering, which enable us to enhance the Seebeck coefficient and decrease the thermal conductivity, respectively 2 – 4 , 10 – 12 .…”
