Unlike commensurate heterostructures, incommensurate ones have often been neglected, due to the rarity in nature and the assumption of suppressed coherent interlayer movement of electrons. How the interlayer interaction affects the electronic structure of such a nonperiodic heterostructure is a fundamental question. In this work, by successfully growing 30°-twisted bilayer graphene (tBLG) as an example for incommensurate “heterostructure” with quasicrystalline order, we report the emergence of mirrored Dirac cones. We identify that these mirrored Dirac cones are a consequence of the interlayer interaction, showing its importance in the incommensurate structure, which has been overlooked before. These results broaden the application range of van der Waals heterostructure for future electronic devices.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383951793965541379","@type":"Researcher","foaf:name":[{"@value":"Wei Yao"}],"jpcoar:affiliationName":[{"@value":"State Key Laboratory of Low Dimensional Quantum Physics, Tsinghua University, Beijing 100084, China;"},{"@value":"Department of Physics, Tsinghua University, Beijing 100084, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541376","@type":"Researcher","foaf:name":[{"@value":"Eryin Wang"}],"jpcoar:affiliationName":[{"@value":"State Key Laboratory of Low Dimensional Quantum Physics, Tsinghua University, Beijing 100084, China;"},{"@value":"Department of Physics, Tsinghua University, Beijing 100084, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541381","@type":"Researcher","foaf:name":[{"@value":"Changhua Bao"}],"jpcoar:affiliationName":[{"@value":"State Key Laboratory of Low Dimensional Quantum Physics, Tsinghua University, Beijing 100084, China;"},{"@value":"Department of Physics, Tsinghua University, Beijing 100084, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541377","@type":"Researcher","foaf:name":[{"@value":"Yiou Zhang"}],"jpcoar:affiliationName":[{"@value":"Department of Physics, The Chinese University of Hong Kong, Hong Kong, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541386","@type":"Researcher","foaf:name":[{"@value":"Kenan Zhang"}],"jpcoar:affiliationName":[{"@value":"State Key Laboratory of Low Dimensional Quantum Physics, Tsinghua University, Beijing 100084, China;"},{"@value":"Department of Physics, Tsinghua University, Beijing 100084, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541380","@type":"Researcher","foaf:name":[{"@value":"Kejie Bao"}],"jpcoar:affiliationName":[{"@value":"Department of Physics, The Chinese University of Hong Kong, Hong Kong, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541387","@type":"Researcher","foaf:name":[{"@value":"Chun Kai Chan"}],"jpcoar:affiliationName":[{"@value":"Department of Physics, The Chinese University of Hong Kong, Hong Kong, China;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541378","@type":"Researcher","foaf:name":[{"@value":"Chaoyu Chen"}],"jpcoar:affiliationName":[{"@value":"Synchrotron SOLEIL, L’Orme des Merisiers, Saint Aubin-BP 48, 91192 Gif sur Yvette Cedex, France;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541382","@type":"Researcher","foaf:name":[{"@value":"Jose Avila"}],"jpcoar:affiliationName":[{"@value":"Synchrotron SOLEIL, L’Orme des Merisiers, Saint Aubin-BP 48, 91192 Gif sur Yvette Cedex, France;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951793965541383","@type":"Researcher","foaf:name":[{"@value":"Maria C.
