The temperature and power dependent carrier lifetime suggests that Shockley\u2013Read\u2013Hall process is the dominant nonradiative recombination mechanism responsible for the carrier relaxation. In addition, the electron scattering with a 14.5 meV optical phonon plays an active role in the carrier relaxation with increasing temperatures. A broad absorption around 1.65\u20131.90 eV is observed. The photocarriers associated with this broad transition show a long lifetime of \u223c200 ps that is nearly independent of temperature and photon energy. This is indicative of bound carriers by defects. Our experimental results provide essential information for the characteristics of carrier dynamics and defects in InSe flakes. The experimental findings are fundamentally important for further development of microelectronics and optoelectronics based on InSe.\n                  <\/jats:p>","DOI":"10.1088\/1361-6528\/ab5835","type":"journal-article","created":{"date-parts":[[2019,11,15]],"date-time":"2019-11-15T18:00:55Z","timestamp":1573840855000},"page":"095713","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Photo-excited carrier relaxation dynamics in two-dimensional InSe flakes"],"prefix":"10.1088","volume":"31","author":[{"given":"Ying","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jialiang","family":"Ye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guihao","family":"Zhai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6046-063X","authenticated-orcid":false,"given":"Yu","family":"Ye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoguang","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0059-6599","authenticated-orcid":false,"given":"Xinhui","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2019,12,12]]},"reference":[{"key":"nanoab5835bib1","doi-asserted-by":"publisher","first-page":"699","DOI":"10.1038\/nnano.2012.193","type":"journal-article","volume":"7","author":"Wang","year":"2012","journal-title":"Nat.
