These phases are gate-tunable and related to the presence of flat electronic bands, isolated by single-particle band gaps. This enables gate-controlled charge confinements, essential for the operation of single-electron transistors (SETs), and allows one to explore the interplay of confinement, electron interactions, band renormalization, and the moiré superlattice, potentially revealing key paradigms of strong correlations. Here, we present gate-defined SETs in tBLG with well-tunable Coulomb blockade resonances. These SETs allow us to study magnetic field-induced quantum oscillations in the density of states of the source-drain reservoirs, providing insight into gate-tunable Fermi surfaces of tBLG. Comparison with tight-binding calculations highlights the importance of displacement-field-induced band renormalization crucial for future advanced gate-tunable quantum devices and circuits in tBLG including, e.g., quantum dots and Josephson junction arrays.}, cin = {PGI-9 / JARA-FIT / HNF}, ddc = {660}, cid = {I:(DE-Juel1)PGI-9-20110106 / $I:(DE-82)080009_20140620$ / I:(DE-Juel1)HNF-20170116}, pnm = {5222 - Exploratory Qubits (POF4-522) / 2D4QT - 2D Materials for Quantum Technology (820254) / DFG project G:(GEPRIS)535377524 - Quantenpunkte in verdrehtem und proximity-gekoppeltem zweilagigen Graphen (535377524) / DFG project G:(GEPRIS)390534769 - EXC 2004: Materie und Licht für Quanteninformation (ML4Q) (390534769) / DFG project G:(GEPRIS)437214324 - Durchstimmbare Twistronics: Lokales Tuning und lokale Detektion topologischer Randzustände und Supraleitung in Zweilagigen-Graphen (437214324) / DFG project G:(GEPRIS)471733165 - Moiré-verstärkte Infrarot-Photodetektion und THz-Emission in verdrehten Graphen-Übergittern (471733165) / DFG project G:(GEPRIS)534269806 - Terahertz-Quantensensorik mit Zweilagigen-Graphen Quantenpunkten in Resonatoren (534269806)}, pid = {G:(DE-HGF)POF4-5222 / G:(EU-Grant)820254 / G:(GEPRIS)535377524 / G:(GEPRIS)390534769 / G:(GEPRIS)437214324 / G:(GEPRIS)471733165 / G:(GEPRIS)534269806}, typ = {PUB:(DE-HGF)16}, doi = {10.1021/acs.nanolett.4c06492}, url = {https://juser.fz-juelich.de/record/1042705}, }
