Seebeck coefficient (α) and resistivity (ρ) of all the samples were measured under magnetic fields of 0-2 T at temperatures of 50-300 K. The magnitude of absolute value of the Seebeck coefficient and the resistivity were ncreased under magnetic fields, and power factor (PF) expressed by α2/ρ was estimated. It was shown that the PF has a maximum value (PF(Bpeak)) at an optimum magnetic field (Bpeak). Then, the magnitude of Bpeak was increased with increasing aspect ratio, which defined a wire length divided by a diameter. Improvement ratio of PF (PF(Bpeak)/PF(0)) in the magnetic field didn’t improve in below 200K using the bulk sample. On the other hand, the ratio improved in measured temperature region on all prepared microwire array samples. PF(Bpeak)/PF(0)　achieved more than 1.5 times using a diameter of 6μm microwire array which had a highest　mobility in the prepared samples. It was found that not only high aspect ratio like the　microwire array sample but also high mobility make it possible to improve the power factor　in a magnetic field.","subitem_description_type":"Abstract"}]},"item_113_description_25":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"指導教員: 埼玉大学大学院理工学研究科准教授 長谷川靖洋","subitem_description_type":"Other"}]},"item_113_description_33":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_113_description_34":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_113_other_language_26":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_113_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学大学院理工学研究科"}]},"item_113_record_name_8":{"attribute_name":"書誌","attribute_value_mlt":[{"subitem_record_name":"平成19年度環境制御システムコース修士論文発表会要旨集"}]},"item_113_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Nakano, Hirofumi"}]},"item_113_text_36":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"GM0000021"}]},"item_113_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科環境制御システムコース環境支援システム講座エコエレクトロニクス研究室"}]},"item_113_text_5":{"attribute_name":"著者 所属（別言語）","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中野, 博文"},{"creatorName":"ナカノ, ヒロフミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-23"}],"displaytype":"detail","filename":"GM0000021.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"GM0000021.pdf","url":"https://sucra.repo.nii.ac.jp/record/10487/files/GM0000021.pdf"},"version_id":"77bc6746-ced9-47e5-b9b0-d12630a9147d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"microwire array","subitem_subject_scheme":"Other"},{"subitem_subject":"power factor","subitem_subject_scheme":"Other"},{"subitem_subject":"Seebeck coefficient","subitem_subject_scheme":"Other"},{"subitem_subject":"crystal orientation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"磁場中におけるマイクロワイヤーアレイ素子のパワーファクター評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"磁場中におけるマイクロワイヤーアレイ素子のパワーファクター評価"}]},"item_type_id":"113","owner":"3","path":["434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-07"},"publish_date":"2008-03-07","publish_status":"0","recid":"10487","relation_version_is_last":true,"title":["磁場中におけるマイクロワイヤーアレイ素子のパワーファクター評価"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T18:49:32.593871+00:00"}
