The monolayer transition-metal dichalcogenides are semiconducting and are unique due to the coupling between the spin and valley degrees of freedom originating from the relativistic spin–orbit interaction. Here, we report the direct observation of valley-dependent out-of-plane spin polarization in an archetypal transition-metal dichalcogenide—MoS2—using spin- and angle-resolved photoemission spectroscopy. The result is in fair agreement with a first-principles theoretical prediction. This was made possible by choosing a 3R polytype crystal, which has a non-centrosymmetric structure, rather than the conventional centrosymmetric 2H form. We also confirm robust valley polarization in the 3R form by means of circularly polarized photoluminescence spectroscopy. Non-centrosymmetric transition-metal dichalcogenide crystals may provide a firm basis for the development of magnetic and electric manipulation of spin/valley degrees of freedom.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"UTokyo Research掲載「バレートロニクス材料の提案」 URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/a-proposed-valleytronics-material/","subitem_description_type":"Other"},{"subitem_description":"UTokyo Research \"A proposed valleytronics material\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/a-proposed-valleytronics-material/","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/nnano.2014.148","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/a-proposed-valleytronics-material/","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/a-proposed-valleytronics-material/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.nature.com/nnano/journal/v9/n8/full/nnano.2014.148.html","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (C) 2014, 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":"AA12163154","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1748-3387","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1748-3395","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Quantum-Phase Electronics Centre (QPEC) and Department of Applied Physics, University of Tokyo"},{"subitem_text_value":"RIKEN Centre for Emergent Matter Science"},{"subitem_text_value":"Institute for Solid State Physics, University of Tokyo"},{"subitem_text_value":"Graduate School of Science, Hiroshima University"},{"subitem_text_value":"Hiroshima Synchrotron Radiation Centre, Hiroshima University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Suzuki, R."}],"nameIdentifiers":[{"nameIdentifier":"2401","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakano, M."}],"nameIdentifiers":[{"nameIdentifier":"2402","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Y.
