Thermoelectric (TE) devices pave a promising pathway for clean and efficient energy conversion between heat and electricity. Among various TE materials, copper selenide (CuSe) has attracted significant interest due to its high electrical conductivity and low thermal conductivity offered by its superionic behavior, making it a candidate for high-performance thermoelectric applications. The present study systematically investigates the TE properties of thin film-based nanocomposites comprised of lead (Pb)-doped CuSe integrated with lead selenide (PbSe) samples.

Indium tin oxide (ITO) has been widely investigated for optoelectronic applications. However, the current study focuses on the thermoelectric aspects of ITO thin films. The thermoelectric transport properties of ITO have been further improved through a facile method of silver (Ag) incorporation into ITO thin films.

Copper selenide (CuSe) has been extensively studied due to its promising thermoelectric properties in bulk form. However, the miniaturization of thermoelectric devices using thin films is highly desired for smart applications. To date, there are few reports on composite thin films of CuSe for thermoelectric applications, primarily due to their lower conversion efficiency.

In this study, we investigate the thermoelectric properties of functionalized multi-walled carbon nanotubes (F-MWCNTs) dispersed over a flexible substrate through a facile vacuum filtration route. To improve their interfacial adhesion and dispersion, F-MWCNTs underwent hot-pressing. The heat-treatment has improved the nanotubes' connections and subsequently reduced porosity as well, which results in an increasing electrical conductivity upon increasing temperature of hot-pressing.

Miniaturization is crucial to realize thermoelectric (TE) devices as an energy source for smart utilities. The present work reports the bulk-like value realized in Cu Se thin films in the mid-temperature range. The effect of varying the film thickness on the structural and TE properties were systematically studied, and the obtained results were compared with that of their bulk counterpart.
