The probed T2SL sample consisted of a 6 μm cutoff p–i–n diode having a 300-period superlattice with a 9-monolayer (ML) GaSb /0.9 ML InSb/7 ML InAs on a p-type GaSb substrate.\n\\nThe absorption quantum efficiency is estimated from the sample transmission at 87 K. We prepared three T2SL samples using GaSb substrates of different thicknesses: 150, 100, and 50 μm. By comparing the transmission spectra of these samples to that of a 100 μm thick GaSb substrate, we derived the absorption coefficient and the absorption quantum efficiency of the T2SL sample. We also discuss the refractive index of T2SL using a thin-film interference method together with the transmission measurements.\n\\nThe external quantum efficiency is measured with a p–i–n detector using the T2SL sample having the same design. The detector consists of a 50-period p-type (Be: 1 × 1017 cm−3) SL, a 200-period undoped SL as absorbing layer, and a 50-period n-type (Si: 1 × 1017 cm−3) SL. The detector responsivity is 0.4 A/W at 4.5 μm and the quantum efficiency is 17% at 30 K.\n\\nThe absorption quantum efficiency was 25% at 4.5 μm when we employed the complete T2SL (300-period T2SL). However, it became 18% when we used the absorption layer (200-period T2SL), which is consistent with the measured external quantum efficiency. This result suggests that almost all the carriers generated in the absorption layer are collected.", "subitem_description_type": "Other"}]}, "item_7_description_32": {"attribute_name": "資料番号", "attribute_value_mlt": [{"subitem_description": "資料番号: PA1510066000", "subitem_description_type": "Other"}]}, "item_7_publisher_9": {"attribute_name": "出版者（英）", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_7_relation_25": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "info:doi/10.1016/j.infrared.2014.10.014"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1016/j.infrared.2014.10.014", "subitem_relation_type_select": "DOI"}}]}, "item_7_source_id_21": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1350-4495", "subitem_source_identifier_type": "ISSN"}]}, "item_7_source_id_24": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10992373", "subitem_source_identifier_type": "NCID"}]}, "item_7_text_35": {"attribute_name": "JAXAカテゴリ", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ: 学術雑誌論文"}]}, "item_7_text_36": {"attribute_name": "JAXAカテゴリ2", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ2: AS"}]}, "item_7_text_43": {"attribute_name": "DSpaceコレクション番号", "attribute_value_mlt": [{"subitem_text_value": "DSpaceコレクション番号: 12"}]}, "item_7_text_7": {"attribute_name": "著者所属（英）", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Japan Aerospace Exploration Agency (JAXA)"}, {"subitem_text_language": "en", "subitem_text_value": "Ritsumeikan University"}, {"subitem_text_language": "en", "subitem_text_value": "Ritsumeikan University"}, {"subitem_text_language": "en", "subitem_text_value": "Sumitomo Electric Industries"}, {"subitem_text_language": "en", "subitem_text_value": "Sumitomo Electric Industries"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "metadata only access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_14cb"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Katayama, Haruyoshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "211389", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takekawa, Tomoko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "211390", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kimata, Masafumi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "211391", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Inada, Hiroshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "211392", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Iguchi, Yasuhiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "211393", "nameIdentifierScheme": "WEKO"}]}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "InAs/GaSb Type-II superlattice", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mid-wavelength infrared", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Absorption", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Quantum efficiency", "subitem_subject_language": "en", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Measurement of absorption and external quantum efficiency of an InAs/GaSb Type II superlattice", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Measurement of absorption and external quantum efficiency of an InAs/GaSb Type II superlattice", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["1888"], "permalink_uri": "https://jaxa.repo.nii.ac.jp/records/22564", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-08-24"}, "publish_date": "2015-08-24", "publish_status": "0", "recid": "22564", "relation": {}, "relation_version_is_last": true, "title": ["Measurement of absorption and external quantum efficiency of an InAs/GaSb Type II superlattice"], "weko_shared_id": -1}
