The addition of C or N to TiNiSn leads to an enhanced power factor and a decreasing lattice thermal conductivity by point defect phonon scattering. The thermoelectric performances of TiNiSn alloys are significantly improved by adding 1 at. % TiN, TiC, and figure of merit (ZT) values of 0.43 and 0.34, respectively, can be obtained at 723 K. This increase in thermoelectric performance is very helpful in the commercialization of thermoelectric power generation in the mid-temperature range.<\/jats:p>","DOI":"10.3390\/ma11020262","type":"journal-article","created":{"date-parts":[[2018,2,9]],"date-time":"2018-02-09T12:46:27Z","timestamp":1518180387000},"page":"262","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Effect of C and N Addition on Thermoelectric Properties of TiNiSn Half-Heusler Compounds"],"prefix":"10.3390","volume":"11","author":[{"given":"Hwan","family":"Dow","sequence":"first","affiliation":[{"name":"Convergence R&D Division, Korea Institute of Ceramic Engineering and Technology, Jinju 52851, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"Convergence R&D Division, Korea Institute of Ceramic Engineering and Technology, Jinju 52851, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0487-5480","authenticated-orcid":false,"given":"Weon","family":"Shin","sequence":"additional","affiliation":[{"name":"Energy Efficient Materials Center, Korea Institute of Ceramic Engineering and Technology, Jinju 52851, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1038\/nmat2090","article-title":"Complex thermoelectric materials","volume":"7","author":"Snyder","year":"2008","journal-title":"Nat.
