Unfortunately, as most current thermoelectric materials achieve zTs above 1.0, ternary tetrahedrite is not a suitable alternative. Still, improvement of its thermoelectric performance has been achieved to zTs \u2248 1 via isovalent doping and composition tuning, but most studies were limited to a single doping element. This project explores the effects of simultaneous doping with nickel and selenium in the thermoelectric properties of tetrahedrite. Simulated properties for different stoichiometric contents of these dopants, as well as the measured thermoelectric properties of the correspondent materials, are reported. One of the samples, Cu11.5Ni0.5Sb4S12.5Se0.5, stands out with a high power factor = 1279.99 \u00b5W\/m\u00b7K2 at 300 K. After estimating the thermal conductivity, a zT = 0.325 at 300 K was obtained for this composition, which is the highest for tetrahedrites for this temperature. However, analysis of the weighted mobility shows the presence of detrimental factors, such as grain boundaries, disorder, or ionized impurity scattering, pointing to the possibility of further improvements.<\/jats:p>","DOI":"10.3390\/ma16030898","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T03:04:44Z","timestamp":1674011084000},"page":"898","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Thermoelectric Properties of Nickel and Selenium Co-Doped Tetrahedrite"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7665-9096","authenticated-orcid":false,"given":"Duarte","family":"Mo\u00e7o","sequence":"first","affiliation":[{"name":"C2TN, DECN, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Campus Tecnol\u00f3gico e Nuclear, 2695-066 Bobadela, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4952-4185","authenticated-orcid":false,"given":"Jos\u00e9 F.","family":"Malta","sequence":"additional","affiliation":[{"name":"C2TN, DECN, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Campus Tecnol\u00f3gico e Nuclear, 2695-066 Bobadela, Portugal"},{"name":"Centre for Physics of the University of Coimbra (CFisUC), Department of Physics, University of Coimbra, 3004-516 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0986-9880","authenticated-orcid":false,"given":"Lu\u00eds F.","family":"Santos","sequence":"additional","affiliation":[{"name":"CQE, Departamento de Engenharia Qu\u00edmica, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1855-7758","authenticated-orcid":false,"given":"Elsa B.","family":"Lopes","sequence":"additional","affiliation":[{"name":"C2TN, DECN, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Campus Tecnol\u00f3gico e Nuclear, 2695-066 Bobadela, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2640-3038","authenticated-orcid":false,"given":"Ant\u00f3nio P.","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"C2TN, DECN, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Campus Tecnol\u00f3gico e Nuclear, 2695-066 Bobadela, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1568","DOI":"10.1016\/j.rser.2015.12.192","article-title":"Estimating the global waste heat potential","volume":"57","author":"Forman","year":"2016","journal-title":"Renew.
