--- res: bibo_abstract: - Twisted bilayer graphene (tBLG) near the flat band condition is a versatile new platform for the study of correlated physics in 2D. Resistive states have been observed at several commensurate fillings of the flat miniband, along with superconducting states near half filling. To better understand the electronic structure of this system, we study electronic transport of graphite gated superconducting tBLG devices in the normal regime. At high magnetic fields, we observe full lifting of the spin and valley degeneracy. The transitions in the splitting of this four-fold degeneracy as a function of carrier density indicate Landau level (LL) crossings, which tilted field measurements show occur between LLs with different valley polarization. Similar LL structure measured in two devices, one with twist angle θ=1.08° at ambient pressure and one at θ=1.27° and 1.33GPa, suggests that the dimensionless combination of twist angle and interlayer coupling controls the relevant details of the band structure. In addition, we find that the temperature dependence of the resistance at B=0 shows linear growth at several hundred Ohm/K in a broad range of temperatures. We discuss the implications for modeling the scattering processes in this system.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Hryhoriy foaf_name: Polshyn, Hryhoriy foaf_surname: Polshyn foaf_workInfoHomepage: http://www.librecat.org/personId=edfc7cb1-526e-11ec-b05a-e6ecc27e4e48 orcid: 0000-0001-8223-8896 - foaf_Person: foaf_givenName: Yuxuan foaf_name: Zhang, Yuxuan foaf_surname: Zhang - foaf_Person: foaf_givenName: Matthew foaf_name: Yankowitz, Matthew foaf_surname: Yankowitz - foaf_Person: foaf_givenName: Shaowen foaf_name: Chen, Shaowen foaf_surname: Chen - foaf_Person: foaf_givenName: Takashi foaf_name: Taniguchi, Takashi foaf_surname: Taniguchi - foaf_Person: foaf_givenName: Kenji foaf_name: Watanabe, Kenji foaf_surname: Watanabe - foaf_Person: foaf_givenName: David E. foaf_name: Graf, David E. foaf_surname: Graf - foaf_Person: foaf_givenName: Cory R. foaf_name: Dean, Cory R. foaf_surname: Dean - foaf_Person: foaf_givenName: Andrea foaf_name: Young, Andrea foaf_surname: Young bibo_issue: '2' bibo_volume: 64 dct_date: 2019^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0003-0503 dct_language: eng dct_publisher: American Physical Society@ dct_title: Normal state transport in superconducting twisted bilayer graphene@ ...
