This is rooted on the speci\ufb01c symmetries of traditionally studied systems, not in a fundamental constraint. Here, we show that the reduced symmetry of strong spin-orbit coupling materials such as MoTe2 or WTe2 enables a new form of canted spin Hall e\ufb00ect (SHE), characterized by large and robust in-plane spin polarizations, which gives rise to an unprecedented charge-to-spin interconversion e\ufb00ect. Through quantum transport calculations on realistic device geometries, including disorder, we found long spin di\ufb00usion lengths (\u03bbs) and a gate tunable charge-to-spin interconversion e\ufb03ciency with an upper value reaching \u03b8xy \u2248 80%. The SHE \ufb01gure of merit \u03bbs\u03b8xy \u223c 1\u201350 nm, can signi\ufb01cantly exceed values of conventional SHE materials, and stems from momentum-invariant (persistent) spin textures together with large spin Berry curvature along the Fermi contour. Speci\ufb01c guidelines for unambiguous experimental con\ufb01rmation are proposed, paving the way towards exploiting such phenomena in spintronic devices. These \ufb01ndings vividly emphasize how crystal symmetry and band topology can govern the intrinsic SHE, and how they may be exploited to broaden the range and e\ufb03ciency of spintronic functionalities.<\/p>","DOI":"10.21203\/rs.3.rs-124172\/v1","type":"posted-content","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T16:05:07Z","timestamp":1609949107000},"source":"Crossref","is-referenced-by-count":2,"title":["Charge-to-Spin Interconversion in Low-Symmetry Topological Materials"],"prefix":"10.21203","author":[{"given":"Marc","family":"Vila","sequence":"first","affiliation":[{"name":"Institut Catal\u00e0 de Nanoci\u00e8ncia i Nanotecnologia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2394-8537","authenticated-orcid":false,"given":"Chuang-Han","family":"Hsu","sequence":"additional","affiliation":[{"name":"Institute of Physics, Academia Sinica, Taipei Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5752-4759","authenticated-orcid":false,"given":"Jose Garcia","family":"Aguilar","sequence":"additional","affiliation":[{"name":"Catalan Institute of Nanoscience and Nanotechnology"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1049-4983","authenticated-orcid":false,"given":"Antonio","family":"Benitez","sequence":"additional","affiliation":[{"name":"Catalan Institute of Nanoscience and Nanotechnology (ICN2), CSIC and The Barcelona Institute of Science and Technology, Campus UAB, Bellaterra, 08193 Barcelona"}]},{"given":"Xavier","family":"Waintal","sequence":"additional","affiliation":[{"name":"CEA Grenoble"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4632-8891","authenticated-orcid":false,"given":"Sergio","family":"Valenzuela","sequence":"additional","affiliation":[{"name":"Catalan Institute of Nanoscience and Nanotechnology (ICN2)"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3462-524X","authenticated-orcid":false,"given":"Vitor","family":"Pereira","sequence":"additional","affiliation":[{"name":"National University of Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0323-4665","authenticated-orcid":false,"given":"Stephan","family":"Roche","sequence":"additional","affiliation":[{"name":"Catalan Institute of Nanoscience and Nanotechnology (ICN2), CSIC and The Barcelona Institute of Science and Technology, Campus UAB, Bellaterra, 08193 Barcelona"}]}],"member":"297","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-124172\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-124172\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T20:00:26Z","timestamp":1634760026000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-124172\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1,6]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-124172\/v1","relation":{},"subject":[],"published":{"date-parts":[[2021,1,6]]},"subtype":"preprint"}}
