To verify the topological nature of the surface states, Bi-based chalcogenides such as Bi2Se3, Bi2Te3, Sb2Te3 and their combined/mixed compounds have been intensively studied. Here, we report the realization of the quantum Hall effect on the surface Dirac states in (Bi1−xSbx)2Te3 films. With electrostatic gate-tuning of the Fermi level in the bulk band gap under magnetic fields, the quantum Hall states with filling factor ±1 are resolved. Furthermore, the appearance of a quantum Hall plateau at filling factor zero reflects a pseudo-spin Hall insulator state when the Fermi level is tuned in between the energy levels of the non-degenerate top and bottom surface Dirac points. The observation of the quantum Hall effect in three-dimensional topological insulator films may pave a way toward topological insulator-based electronics.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"UTokyo Research掲載「トポロジカル絶縁体の表面ディラック状態の量子化を実証」 URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/observation-of-quantization-in-surface-dirac-states-of-topological-insulator.html","subitem_description_type":"Other"},{"subitem_description":"UTokyo Research \"Observation of quantization in surface Dirac states of topological insulator\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/observation-of-quantization-in-surface-dirac-states-of-topological-insulator.html","subitem_description_type":"Other"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature Publishing Group"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1038/ncomms7627","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/observation-of-quantization-in-surface-dirac-states-of-topological-insulator.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/observation-of-quantization-in-surface-dirac-states-of-topological-insulator.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.nature.com/ncomms/2015/150414/ncomms7627/abs/ncomms7627.html","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2015, Rights Managed by Nature Publishing Group"}]},"item_2_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12645905","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"20411723","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Applied Physics and Quantum-Phase Electronics Center (QPEC), University of Tokyo"},{"subitem_text_value":"Institute for Materials Research, Tohoku University"},{"subitem_text_value":"PRESTO, Japan Science and Technology Agency (JST)"},{"subitem_text_value":"RIKEN Center for Emergent Matter Science (CEMS)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yoshimi, R."}],"nameIdentifiers":[{"nameIdentifier":"2623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukazaki, A."}],"nameIdentifiers":[{"nameIdentifier":"2624","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kozuka, Y."}],"nameIdentifiers":[{"nameIdentifier":"2625","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Falson, J."}],"nameIdentifiers":[{"nameIdentifier":"2626","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, K.
