“…CrN is a flagship material among the family of hard coatings due to its hardness, optimal wear resistance and thermal stability [8]. It can be deposited using a variety of commercial PVD techniques: electron beam, cathodic arc and magnetron sputtering [8]. On the other hand, WC-C belongs to a group of materials so called tribological coatings, having low friction and therefore low adhesive strength, making it suitable for load bearing components [6,9].…”

“…For such purposes CrN has excellent mechanical properties such as high hardness (∼28 GPa), high corrosion resistance, and excellent wear properties. [136][137][138][139][140][141][142] CrN is easy to synthesis as a thin film by magnetron sputtering (DC, pulsed DC, middle frequency RF, or High Power Impulse). [141][142][143][144][145][146][147] CrN thin films can be grown with a very low internal stresses, thus it can be synthesized in various thickness from thin to thick coatings (100 nm to 100 µm) on a variety of steels and engineering ceramics with very good adhesion.…”

Thermoelectric devices are one of the promising energy harvesting technologies, because of their ability to convert heat (temperature gradient) to electricity by the Seebeck effect. Furthermore, thermoelectric devices can be used for cooling or heating by the inverse effect (Peltier effect). Since this conversion process is clean, with no emission of greenhouse gases during the process, this technology is attractive for recovering waste heat in automobiles or industries into usable electricity. However, the conversion efficiency of such devices is rather low due to fundamental materials limitations manifested through the thermoelectric figure of merit (ZT ). Thus, there is high demand on finding materials with high ZT or strategies to improve ZT of materials.In this thesis, I discuss the basics of thermoelectrics and how to improve ZT of materials, including present-day strategies. Based on these ideas, I propose a new class of materials for thermoelectric applications: transition-metal nitrides, mainly ScN, CrN and their solid solutions. Here, I employed both experimental and theoretical methods to synthesize and study their thermoelectric properties. My study envisages ways for improving the thermoelectric figure of merit of ScN and possible new materials for thermoelectric applications.The results of my studies show that ScN is a promising thermoelectric material since it exhibits high thermoelectric power factor 2.5×10 −3 Wm −1 K −2 at 800 K, due to low metallic-like electrical resistivity while retained relatively large Seebeck coefficient. My studies on thermal conductivity of ScN also suggest a possibility to control thermal conductivity by tailoring the microstructure of ScN thin films. Furthermore, my theoretical studies on effects of impurities and stoichiometry on the electronic structure of ScN suggest the possibly to improve ScN ZT by stoichiometry tuning and doping. For CrN and Cr1−xScxN solid solution thin films, the results show that the power factor of CrN (8×10 −4Wm −1 K −2 at 770 K) can be retained for the solid solution Cr0.92Sc0.08N. Finally, density functional theory was used to enable a systematic predictionbased strategy for optimizing ScN thermoelectric properties via phase stability of solid solutions. Sc1−xGdxN and Sc1−xLuxN are stabilized as disordered solid solutions, while in the Sc-Nb-N and Sc-Ta-N systems, the inherently layered ternary structures ScNbN2 and ScTaN2 are stable. Svensk sammanfattningSedan den industriella revolutionen har fossila bränslen varit vår huvudkälla till energi i motorer för transport, elproduktion och uppvärmning av byggnader. Eftersom mänskligheten och vår teknik växer för varje år som går, fortsätter efterfrågan på fossila bränslen att öka. Med tanke på att fossila bränslen inte är förnybara, riskerar vi att de tar slut. Dessutom är resultatet av denna ständiga förbränning av fossila bränslen generering av växthusgaser, t.ex. kolmonoxid och koldioxid, som orsakar klimatförändringar, som ett ytterligare problem. Således finns det ett ökande behov...

“…CrN has a variety of applications such as on automotive components [9], machining tools [10], replacement for electroplated Cr [11] and molds for plastics processing [12]. On the other hand, chromium boride coatings are promising candidates for protective coatings such as tools, molds and dies due to their high hardness and good oxidation resistance [13][14][15].…”
