In this study, we investigated the macroscopic in-plane thermal conductivity (\u03ba) and thermal interface conductance (g) of large-area (mm<jats:sup>2<\/jats:sup>) thin film made from MoS<jats:sub>2<\/jats:sub>nanoflakes via liquid exfoliation and deposited on Si\/SiO<jats:sub>2<\/jats:sub>substrate. We found \u03ba and g to be 1.5\u2009W\/mK and 0.23\u2009MW\/m<jats:sup>2<\/jats:sup>K, respectively. These values are much lower than those of single flakes. This difference shows the effects of interconnections between individual flakes on macroscopic thin film parameters. The properties of a Gaussian laser beam and statistical optothermal Raman mapping were used to obtain sample parameters and significantly improve measurement accuracy. This work demonstrates how to address crucial stability issues in light-sensitive materials and can be used to understand heat management in MoS<jats:sub>2<\/jats:sub>and other 2D flake-based thin films.<\/jats:p>","DOI":"10.1038\/s41598-019-49980-7","type":"journal-article","created":{"date-parts":[[2019,9,16]],"date-time":"2019-09-16T10:05:08Z","timestamp":1568628308000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Thermal properties of thin films made from MoS2 nanoflakes and probed via statistical optothermal Raman method"],"prefix":"10.1038","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7740-9651","authenticated-orcid":false,"given":"Arkadiusz P.","family":"Gertych","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"\u0141api\u0144ska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karolina","family":"Czerniak-\u0141osiewicz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Du\u017cy\u0144ska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariusz","family":"Zdrojek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaros\u0142aw","family":"Judek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,9,16]]},"reference":[{"key":"49980_CR1","doi-asserted-by":"publisher","first-page":"263","DOI":"10.1038\/nchem.1589","volume":"5","author":"M Chhowalla","year":"2013","unstructured":"Chhowalla, M. et al.
