Herein, based on non-equilibrium Green\u2019s function combined with density functional theory, we investigated spin-dependent PGE phenomena in the BiC photodetector with the linearly polarized light and zero bias. Due to the presence of strong spin\u2013orbit interaction (SOI) and <jats:italic>C<\/jats:italic>\n                  <jats:sub>3<jats:italic>v<\/jats:italic>\n                  <\/jats:sub> symmetry for the BiC monolayer, the armchair and zigzag BiC photodetectors can produce robust spin-dependent PGEs which possess the cos(2<jats:italic>\u03b8<\/jats:italic>) and sin(2<jats:italic>\u03b8<\/jats:italic>) relations on the photon energies, respectively. Especially, the pristine armchair and armchair Bi-vacancy BiC photodetectors can produce fully spin polarization, and pure spin current was found in the pristine armchair and zigzag BiC photodetector, respectively. Furthermore, after introducing the Bi-vacancy, C-vacancy, Bi-doping and C-doping respectively, the BiC photodetector can produce higher spin-dependent PGEs for their <jats:italic>C<\/jats:italic>\n                  <jats:sub>\n                     <jats:italic>s<\/jats:italic>\n                  <\/jats:sub> symmetry. Additionally, the behaviors of spin-dependent photoresponse are highly anisotropic which can be tuned by the photon energy. This work suggested great potential applications of the BiC monolayer on PGE-driven photodetectors in low energy-consumption optoelectronics and spintronic devices.<\/jats:p>","DOI":"10.1088\/1361-6528\/ad090b","type":"journal-article","created":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T22:51:41Z","timestamp":1698965501000},"page":"065201","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Robust photogalvanic effect, full spin polarization and pure spin current in the BiC photodetector by vacancy and substitution-doping"],"prefix":"10.1088","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2241-0900","authenticated-orcid":false,"given":"Xi","family":"Fu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaozheng","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenhu","family":"Liao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiyuan","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowu","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haixia","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2023,11,21]]},"reference":[{"key":"nanoad090bbib1","doi-asserted-by":"publisher","first-page":"153","DOI":"10.1038\/nphys551","article-title":"Challenges for semiconductor spintronics","volume":"3","author":"Awschalom","year":"2007","journal-title":"Nat.
