By exploiting the quadratic band dispersion of bilayer graphene, we control the Fermi velocity and thus the coherence length via the application of electrostatic gating. Tunneling spectroscopy of the Andreev bound states reveals a crossover from short to long Josephson junction regimes as we approach the charge neutral point of the bilayer graphene. Furthermore, analysis of different mode numbers of the Andreev energy spectrum allows us to estimate the phase-dependent Josephson current quantitatively. Our work provides a new way for studying multi-mode Andreev levels by tuning the Fermi velocity. description_type: abstract lang: en ## Creator - name: Geon-Hyoung Park role: author - name: Wonjun Lee role: author - name: Sein Park role: author - name: Kenji Watanabe role: author orcid: https://orcid.org/0000-0003-3701-8119 organization: National Institute for Materials Science - name: Takashi Taniguchi role: author orcid: https://orcid.org/0000-0002-1467-3105 organization: National Institute for Materials Science - name: Gil Young Cho role: author - name: Gil-Ho Lee role: author ## Contact agent ## Publisher organization: American Physical Society (APS) ## Managing organization ## Keyword - subject: Andreev bound states schema: not_defined - subject: Bilayer graphene schema: not_defined - subject: Josephson junction schema: not_defined ## Rights - description: "© 2024 American Physical Society" identifier: http://rightsstatements.org/vocab/InC/1.0/ ## Other identifier(s) ## Data origin - data_origin_type: other ## Embargo ## Journal - title: Physical Review Letters issn: '10797114' volume: '132' issue: '22' start_page: 226301 end_page: 226301 article_number: '226301' ## Conference ## Related item ## Funding - identifier: 2021R1A6A1A10042944 funder_name: National Research Foundation of Korea - identifier: 2022M3H4A1A04074153 funder_name: National Research Foundation of Korea - identifier: RS-2023-00207732 funder_name: National Research Foundation of Korea - identifier: RS-2023-00208291 funder_name: National Research Foundation of Korea - identifier: 2023M3K5A1094810 funder_name: National Research Foundation of Korea - identifier: 2023M3K5A1094813 funder_name: National Research Foundation of Korea - identifier: IITP-2022-RS-2022-00164799 funder_name: Ministry of Science and ICT, South Korea - identifier: FA2386-22-1-4061 funder_name: Air Force Office of Scientific Research - identifier: IBS-R014-D1 funder_name: Institute of Basic Science - identifier: SSTF-BA2101-06 funder_name: Samsung Science and Technology Foundation - identifier: SSTF-BA2002-05 funder_name: Samsung Science and Technology Foundation - identifier: IO201207-07801-01 funder_name: Samsung - identifier: 21H05233 funder_name: Japan Society for the Promotion of Science - identifier: 23H02052 funder_name: Japan Society for the Promotion of Science - funder_name: Ministry of Education, Culture, Sports, Science and Technology - identifier: 2021R1A6A1A10042944 funder_name: Basic Science Research Institute Fund - funder_name: World Premier International Research Center Initiative ## Instrument ## Instrument operator ## Instrument managing organization ## Measurement method ## Specimen ## Chemical composition ## Structure for specimen ## Structural feature for specimen ## Specific property for specimen ## Process for specimen treatment ## Computational method ## Energy level/transition state ## Software ## Custom property ## Fileset - id: fa7225df-cea9-45e8-ad80-e7ce05d3430f filename: 2024A00643G_Main_text_20240404.docx content_type: application/vnd.openxmlformats-officedocument.wordprocessingml.document size: 836322 md5: 0ed4aff6a19a24fb8b1514b7603ed912 - id: fab502f6-e66d-4dde-9177-d92791c2809b filename: 2024A00643G_Supplemental Material.docx content_type: application/vnd.openxmlformats-officedocument.wordprocessingml.document size: 2430564 md5: 01d6a424e66106ff00bb58c1ae8e65a4 ## Thumbnail fileset_id: fa7225df-cea9-45e8-ad80-e7ce05d3430f filename: 2024A00643G_Main_text_20240404.docx
