It has been found that the dark exciton has a strong influence on the optical properties. The most visible influence is the strongly reduced excitonic emission compared to the biexcitonic one. Temperature dependent lifetime measurements have allowed us to measure a large splitting of $\\Delta E = 6 $ meV between the dark and the bright exciton as well as the spin flip rates between these two states.","authors_text":"Adrien Tribu (SP2M), Catherine Bougerol-Chaillout (NEEL), Gregory Sallen (NEEL), Jean-Philippe Poizat (NEEL), Kuntheak Kheng (SP2M), Lucien Besombes (NEEL), R\\'egis Andr\\'e (NEEL), Serge Tatarenko (NEEL), Thomas Aichele (NEEL)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2009-03-03T11:36:43Z","title":"Dark exciton optical spectroscopy of a semiconducting quantum dot embedded in a nanowire"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0903.0497","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:7059aa26aa65d31336fe25c04f8a05898fecca8cdd13171ac6d6165a1065ec53","target":"record","created_at":"2026-05-18T03:24:07Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"68fdc841a8fdedd54ca096731de8f4490c92d4e90775279998896d9bdc8ebf9d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2009-03-03T11:36:43Z","title_canon_sha256":"5fdaea190225f6aa4dcaa4b44f9736a34d9815d931974e28e531b22480f37d62"},"schema_version":"1.0","source":{"id":"0903.0497","kind":"arxiv","version":1}},"canonical_sha256":"a2975a6add48d19ac49609d369f79f6cfb4e25e88202cb3b840586188e0952a0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a2975a6add48d19ac49609d369f79f6cfb4e25e88202cb3b840586188e0952a0","first_computed_at":"2026-05-18T03:24:07.704938Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:24:07.704938Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uewrQPnn57Kv+Di2zbNgO5qZBhmEk3Y/AQeCUBCNZ0bqaAiGn5BuS1TOmKxS31LwBKzZYISJazY9YBCWvAhBAg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:24:07.705538Z","signed_message":"canonical_sha256_bytes"},"source_id":"0903.0497","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7059aa26aa65d31336fe25c04f8a05898fecca8cdd13171ac6d6165a1065ec53","sha256:666e6ae690b50f7f10e969ae8437f8d3f1794b68955701b6717e7d16f39dc87b"],"state_sha256":"de1b4f7ae239e151a89d0685141278ddedce27d0e743cfcaeee2a5ff80123d28"}
