Based on one-electron band theory, features observed at -3.4 and 3.6 eV relative to the valence-band maximum (VBM) are ascribed to emission from the Mn 3d↑ and 3d↓ states with eg symmetry, respectively, providing a Mn 3d spin-exchange splitting energy (Ueff) of 7.0±0.2 eV. This value compares well with the value predicted in the theoretical investigation of electronic structures and magnetic properties of Cd1-xMnxTe. With increasing Mn concentration, the energy position of the conduction-band minimum shifts almost linearly toward higher energy relative to the VBM as a result of an increasing contribution of the higher-lying Mn 4s level relative to the Cd 5s level.    Mn 3d partial DOS's in the valence-band region of Cd1-xMnxTe have been determined from resonant photoemission spectroscopy in the Mn 3p-3d core excitation region. The partial DOS's reveal an appreciable contribution of the Mn 3d states to the top 9 eV of valence bands with three structures; valence bands at 0~-2.5 eV, a main peak at -3.4 eV and a multielectron satellite at -5~-9 eV. These features are almost independent of the Mn concentration. Apart from one-electron band theory, the whole spectrum including the multielectron satellite is found to be well reproduced in terms of the configuration interaction theory using a Mn2+(Te2-)4 model cluster.    Electronic structures of zinc-blende MnTe epitaxial films have also been investigated by means of UPS and IPES. The Ueff-value of zinc-blende MnTe is in good agreement with those of Cd1-xMnxTe and Zn 1-xMnxTe. The width of valence bands and Ueff are by 1.3 eV narrower and by 0.3 eV larger than those of NiAs-type MnTe, respectively.","subitem_description_language":"en"},{"subitem_description":"Contents  Abstract / p1  Chapter1.Introduction / p2  　References / p7  Chapter2.General description of photoemission and inverse-photoemission spectroscopies / p10  　2-1.Photoemission spectroscopy / p10  　2-2.Inverse-photoemission spectroscopy / p13  　References / p17  Chapter3.Hot wall epitaxy(HWE) / p18  　3-1.HWE method / p18  　3-2.Details of the HWE apparatus for DMS / p20  　References / p28  Chapter4.Experimental details I:ultraviolet photoemission and inverse-photoemission study / p29  　4-1.Ultraviolet photoemission and inverse-photoemission spectrometers / p29  　4-2.Sample preparation / p33  　References / p45  Chapter5.Experimental details II:Resonant photoemission spectroscopy / p47  　5-1.Photoemission measurements at SOR-RING / p47  　5-2.Sample preparation / p47  　References / p49  Chapter6.Results and discussion / p50  　6-1.Photoemission and inverse-photoemission study of Cd1-xMnxTe / p50  　6-2.Photoemission and inverse-photoemission study of zinc-blende MnTe / p71  　References / p77  Chapter7 Conclusion / p80  Acknowledgments / p82","subitem_description_type":"TableOfContents"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186819068":{"attribute_name":"Identifier Registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.11501/3131496","subitem_identifier_reg_type":"JaLC"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"1"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicPageStart":"1"}]},"item_1617187087799":{"attribute_name":"Dissertation Number","attribute_value_mlt":[{"subitem_dissertationnumber":"乙第2931号"}]},"item_1617187112279":{"attribute_name":"Degree Name","attribute_value_mlt":[{"subitem_degreename":"博士(理学)","subitem_degreename_language":"ja"},{"subitem_degreename":"Physical Science","subitem_degreename_language":"en"}]},"item_1617187136212":{"attribute_name":"Date Granted","attribute_value_mlt":[{"subitem_dategranted":"1997-02-10"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"(1)Mn 3d states of Cd1-xMnxTe (Cd1-xMnxTeのMn3d状態) 1冊, 共著者 三村功次郎、佐藤仁、原田次郎、宮崎圭司、谷口雅樹、植田義文, (学術誌) Journal of Magnetism and Magnetic Materials 140-144, 2017-2018 (1995).
