The C8-BTBT layers possess the (001) out-of-plane orientation irrespective of the layer thickness and preparation temperature. The C8-BTBT grains are growing up in direction parallel to the substrate surface keeping almost constant height, and the continuous layer is formed by the coalescence of the C8-BTBT grains. The grain size of the continuous C8-BTBT layer increases with raise in preparation temperature. The optical band gap energy could be estimated to be 3.32–3.35 eV regardless of the layer thickness and preparation temperature. The electrical resistivity decreases from 2.1x106 to 1.2x102Ωcm with increase in the preparation temperature due to the increase in the grain size, and the light irradiation induce the drastical decrease to 42–28Ωcm."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "C8-BTBT"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "pssa.201700862.pdf", "filesize": [{"value": "820 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 820000.0, "url": {"url": "https://meral.edu.mm/record/2060/files/pssa.201700862.pdf"}, "version_id": "4aa2d014-c041-4c66-ae1d-c0699a585fb8"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Physics Status Solidi"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Aye Myint Moh"}, {"subitem_authors_fullname": "Khoo, Pei Loon"}, {"subitem_authors_fullname": "Sasaki, Kimihiro"}, {"subitem_authors_fullname": "Watase, Seiji"}, {"subitem_authors_fullname": "Shinagawa, Tsutomu"}, {"subitem_authors_fullname": "Izaki, Masanobu"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2018"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://uyr.uy.edu.mm/handle/123456789/626"}, "item_title": "Growth and Characteristics of C8-BTBT Layer on C-Sapphire Substrate by Thermal Evaporation", "item_type_id": "21", "owner": "1", "path": ["1582967549708"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002060", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2060", "relation": {}, "relation_version_is_last": true, "title": ["Growth and Characteristics of C8-BTBT Layer on C-Sapphire Substrate by Thermal Evaporation"], "weko_shared_id": -1}
