But the family-specific maximum\n            <jats:italic>T<\/jats:italic>\n            <jats:sub>c<\/jats:sub>\n            can be surpassed by application of pressure, a compelling observation known for decades. We investigate the phenomenon with high-pressure anvil cell NMR and measure the charge content at planar Cu and O, and with it the doping of the ubiquitous CuO\n            <jats:sub>2<\/jats:sub>\n            plane with atomic-scale resolution. We find that pressure increases the overall hole doping, as widely assumed, but when it enhances\n            <jats:italic>T<\/jats:italic>\n            <jats:sub>c<\/jats:sub>\n            above what can be achieved by doping, pressure leads to a hole redistribution favoring planar O. This is similar to the observation that the family-specific maximum\n            <jats:italic>T<\/jats:italic>\n            <jats:sub>c<\/jats:sub>\n            is higher for materials where the hole content at planar O is higher at the expense of that at planar Cu. The latter reflects dependence of the maximum\n            <jats:italic>T<\/jats:italic>\n            <jats:sub>c<\/jats:sub>\n            on the Cu\u2013O bond covalence and the charge-transfer gap. The results presented here indicate that the pressure-induced enhancement of the maximum\n            <jats:italic>T<\/jats:italic>\n            <jats:sub>c<\/jats:sub>\n            points to the same mechanism.\n          <\/jats:p>","DOI":"10.1073\/pnas.2215458120","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T20:46:43Z","timestamp":1673038003000},"update-policy":"http:\/\/dx.doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":1,"title":["How pressure enhances the critical temperature of superconductivity in YBa\n            <sub>2<\/sub>\n            Cu\n            <sub>3<\/sub>\n            O\n            <sub>\n              6+\n              <i>y<\/i>\n            <\/sub>"],"prefix":"10.1073","volume":"120","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-1058-3532","authenticated-orcid":false,"given":"Michael","family":"Jurkutat","sequence":"first","affiliation":[{"name":"Felix Bloch Institute for Solid State Physics, Leipzig University 04103, Leipzig, Germany"}]},{"given":"Carsten","family":"Kattinger","sequence":"additional","affiliation":[{"name":"Felix Bloch Institute for Solid State Physics, Leipzig University 04103, Leipzig, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-5347-3002","authenticated-orcid":false,"given":"Stefan","family":"Tsankov","sequence":"additional","affiliation":[{"name":"Felix Bloch Institute for Solid State Physics, Leipzig University 04103, Leipzig, Germany"}]},{"given":"Richard","family":"Reznicek","sequence":"additional","affiliation":[{"name":"Felix Bloch Institute for Solid State Physics, Leipzig University 04103, Leipzig, Germany"}]},{"given":"Andreas","family":"Erb","sequence":"additional","affiliation":[{"name":"Walther Meissner Institut, Bayerische Akademie der Wissenschaften 85748, Garching, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-0140-6964","authenticated-orcid":false,"given":"J\u00fcrgen","family":"Haase","sequence":"additional","affiliation":[{"name":"Felix Bloch Institute for Solid State Physics, Leipzig University 04103, Leipzig, Germany"}]}],"member":"341","published-online":{"date-parts":[[2023,1,6]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01303701"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature14165"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevB.90.140504"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms11413"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2106476118"},{"key":"e_1_3_4_6_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1073\/pnas.2207449119","article-title":"On the electron pairing mechanism of copper-oxide high temperature superconductivity","volume":"119","author":"O\u2019Mahony S.
