In this work, using suspended single-walled carbon nanotubes, electric field effects on photoluminescence is investigated. It is expected that energy shifts would be caused by screening effects due to doped carriers by the electric field. In order to allow an application of electric fields on as-grown nanotubes, back-gated field effect transistors are used. Trenches are fabricated on SiO2/Si substrates, and Pt is deposited for electrical contacts. Carbon nanotubes are grown by patterned chemical vapor deposition. Individual suspended carbon nanotubes are identified by taking photoluminescence images using a home-built laser-scanning confocal microscope. After determining the chirality by photoluminescence excitation spectra, we measure the gate voltage dependence on photoluminescence. We observe quenching of photoluminescence intensity and blue shifts of emission wavelength as gate voltages are applied. Screening effects are not observed. A possible cause of the energy shifts is migration of adsorbed molecules due to the electric field. Theoretical calculation of the photoluminescence quenching caused by the increase of scattering with carriers is compared with experimental results.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "9906", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u5b89\u6cb3\u5185, \u8aed"}]}]}, "item_7_select_21": {"attribute_name": "\u5b66\u4f4d", "attribute_value_mlt": [{"subitem_select_item": "master"}]}, "item_7_subject_13": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "549", "subitem_subject_scheme": "NDC"}]}, "item_7_text_24": {"attribute_name": "\u7814\u7a76\u79d1\u30fb\u5c02\u653b", "attribute_value_mlt": [{"subitem_text_value": "\u5de5\u5b66\u7cfb\u7814\u7a76\u79d1\u96fb\u6c17\u7cfb\u5de5\u5b66\u5c02\u653b"}]}, "item_7_text_36": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Thesis"}]}, "item_7_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5927\u5b66\u9662\u5de5\u5b66\u7cfb\u7814\u7a76\u79d1\u96fb\u6c17\u7cfb\u5de5\u5b66\u5c02\u653b"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yasukochi, Satoshi"}], "nameIdentifiers": [{"nameIdentifier": "9905", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "37096510.pdf", "filesize": [{"value": "6.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 6600000.0, "url": {"label": "37096510.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/4352/files/37096510.pdf"}, "version_id": "abeb652c-e0c3-4f11-9f22-e0425de15f92"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Electric Field Dependence of Photoluminescence from Single-Walled Carbon Nanotubes", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Electric Field Dependence of Photoluminescence from Single-Walled Carbon Nanotubes"}]}, "item_type_id": "7", "owner": "1", "path": ["9/233/234", "6/209/271"], "permalink_uri": "http://hdl.handle.net/2261/53514", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2013-04-01"}, "publish_date": "2013-04-01", "publish_status": "0", "recid": "4352", "relation": {}, "relation_version_is_last": true, "title": ["Electric Field Dependence of Photoluminescence from Single-Walled Carbon Nanotubes"], "weko_shared_id": null}
