However, in heavily doped semiconductors, the impurities substantially disturb the band ordering, leading to significant degradation in performance. Here, we present the unexpected finding that the band ordering is suddenly restored in Mn-doped GaAs ((Ga,Mn)As) when the Mn concentration slightly exceeds B0.7% despite the extremely high doping concentration; this phenomenon is very difficult to predict from the general behaviour of doped semiconductors. This phenomenon occurs with a ferromagnetic phase transition, which is considered to have a crucial role in generating a well-ordered band structure. Our findings offer possibilities for ultra-high-speed quantum-effect spin devices based on semiconductors.", "subitem_description_type": "Abstract"}]}, "item_2_description_6": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "UTokyo Research\u63b2\u8f09\u300c\u534a\u5c0e\u4f53\u306e\u57fa\u790e\u7269\u7406\u5b66\u3067\u65b0\u305f\u306a\u767a\u898b\u300d URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/new-discovery-in-semiconductor-physics.html", "subitem_description_type": "Other"}, {"subitem_description": "UTokyo Research \"New discovery in semiconductor physics\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/new-discovery-in-semiconductor-physics.html", "subitem_description_type": "Other"}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "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/ncomms12013", "subitem_relation_type_select": "DOI"}}]}, "item_2_relation_25": {"attribute_name": "\u95a2\u4fc2URI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/new-discovery-in-semiconductor-physics.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/new-discovery-in-semiconductor-physics.html", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://dx.doi.org/10.1038/ncomms12013", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 The Author(s) 2016.
