“…A more number of sensors can be accommodated on a specific area with standard thin film deposition techniques or screen-printing based methods to obtain temperature mapping of an area with high resolution. Further, the existing thermoelectric energy conversion devices/generators are usually manufactured from toxic and expensive semiconductors such as bismuth tellurides, led tellurides, and their alloys [26] , [27] , [28] . Therefore, the current thermoelectric research is focused on finding low-cost and non-toxic thermoelectric conductors for the application [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] .…”

“…The color of the coatings changed from pale yellow to light brown, then to black corresponding to deposition at the ambient temperature, and 300 and 500 • C, respectively. It was revealed that nanocrystalline V 2 O 5 thin coatings with a [1] preferred orientation and a crystalline grain size of 17.7 nm grew on amorphous glass substrates at temperatures as low as 300 • C. Increasing the substrate temperature to 400 • C resulted in polycrystalline coatings with an average grain size of 11.4 nm [120].…”

Oxide coatings are corrosion resistant at elevated temperatures. They also show intensive phonon scattering and strong quantum confinement behavior. Such features allow them to be used as new materials for thermoelectric energy conversion and temperature measurement in harsh environments. This paper provides an overview on processing thermoelectric oxide coatings via various technologies. The first part deals with the thermoelectricity of materials. A comparison on the thermoelectric behavior between oxides and other materials will be made to show the advantages of oxide materials. In the second part of the paper, various processing technologies for thermoelectric metal oxide coatings in forms of thin film, superlattice, and nanograin powder will be presented. Vapor deposition, liquid phase deposition, nanocasting, solid state approach, and energy beam techniques will be described. The structure and thermoelectric property of the processed metal oxide coatings will be discussed. In addition, the device concept and applications of oxide coatings for thermoelectric energy conversion and temperature sensing will be mentioned. Perspectives for future research will be provided as well.

“…In most applications, ZnO is used in the form of nanowires or nanorods to obtain devices with enhanced properties due to the high surface-to-volume ratio of the active material 14 , 15 . ZnO nanowires can be synthesized by a variety of methods, including chemical vapour deposition 16 , thermal evaporation 17 , molecular beam epitaxy 18 , pulsed laser deposition 19 , hydrothermal synthesis 20 , atomic layer deposition (ALD) 21 , 22 , and thermal oxidation of Zn foil/thin films 23 – 28 or pre-grown Zn nanowires 29 – 31 . Among these methods, thermal oxidation of Zn is one of the most favorable as it does not require high-tech equipment, harmful chemicals, or very high synthesis temperatures and results in a high yield of ZnO nanowires.…”

The near-room temperature thermoelectric properties of self-assembling ZnO nanowire networks before and after encapsulation in nonconductive polymers are studied. ZnO nanowire networks were synthesized via a two-step fabrication technique involving the deposition of metallic Zn networks by thermal evaporation, followed by thermal oxidation. Synthesized ZnO nanowire networks were encapsulated in polyvinyl alcohol (PVA) or commercially available epoxy adhesive. Comparison of electrical resistance and Seebeck coefficient of the ZnO nanowire networks before and after encapsulation showed a significant increase in the network's electrical conductivity accompanied by the increase of its Seebeck coefficient after the encapsulation. The thermoelectric power factor (PF) of the encapsulated ZnO nanowire networks exceeded the PF of bare ZnO networks by ~ 5 and ~ 185 times for PVA- and epoxy-encapsulated samples, respectively, reaching 0.85 μW m−1 K−2 and ZT ~ 3·10–6 at room temperature, which significantly exceeded the PF and ZT values for state-of-the-art non-conductive polymers based thermoelectric flexible films. Mechanisms underlying the improvement of the thermoelectrical properties of ZnO nanowire networks due to their encapsulation are discussed. In addition, encapsulated ZnO nanowire networks showed excellent stability during 100 repetitive bending cycles down to a 5 mm radius, which makes them perspective for the application in flexible thermoelectrics.
