Here we show measurements of a dual-graphite-gated twisted bilayer graphene device, which minimizes charge inhomogeneity. We observe new correlated phases, including for the first time a SC pocket near half-filling of the electron-doped band and resistive states at quarter-filling of both bands that emerge in a magnetic field. Changing the layer polarization with vertical electric field reveals an unexpected competition between SC and correlated insulator phases, which we interpret to result from differences in disorder of each graphene layer and underscores the spatial inhomogeneity like twist angle as a significant source of disorder in these devices [1]."}],"article_number":"R14.00004","_id":"10725","conference":{"name":"APS: American Physical Society","location":"Boston, MA, United States","start_date":"2019-03-04","end_date":"2019-03-08"},"author":[{"last_name":"Chen","full_name":"Chen, Shaowen","first_name":"Shaowen"},{"last_name":"Yankowitz","full_name":"Yankowitz, Matthew","first_name":"Matthew"},{"id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48","last_name":"Polshyn","orcid":"0000-0001-8223-8896","first_name":"Hryhoriy","full_name":"Polshyn, Hryhoriy"},{"first_name":"Kenji","full_name":"Watanabe, Kenji","last_name":"Watanabe"},{"last_name":"Taniguchi","full_name":"Taniguchi, Takashi","first_name":"Takashi"},{"first_name":"David E.","full_name":"Graf, David E.","last_name":"Graf"},{"last_name":"Young","first_name":"Andrea","full_name":"Young, Andrea"},{"last_name":"Dean","first_name":"Cory R.","full_name":"Dean, Cory R."}],"alternative_title":["Bulletin of the American Physical Society"],"related_material":{"link":[{"relation":"used_in_publication","url":"https://arxiv.org/abs/1808.07865"}]}}
