We show by means of first principles density functional theory calculations that the pentagon-heptagon Stone-Wales defect is an ultraviolet emitter and its optical properties closely follow the characteristics of a 4.08-eV quantum emitter often observed in polycrystalline hexagonal boron nitride. We also show that the square-octagon Stone-Wales line defects are optically active in the ultraviolet region with varying gaps depending ","authors_text":"Adam Gali, Gerg\\H{o} Thiering, Hanen Hamdi, Viktor Iv\\'ady, Zolt\\'an Bodrog","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2020-08-16T08:29:59Z","title":"Stone-Wales defects in hexagonal boron nitride as ultraviolet emitters"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2008.06857","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":"sha256:5aead43186976f0b01509f9300187cd091fc9e91e203f70874e74d9dda9d94fe","target":"record","created_at":"2026-07-05T02:05:42Z","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":"539bf1db3de4f7ffdabbd02efcc27d808b80bce9b580fa0588fe58f25231921b","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2020-08-16T08:29:59Z","title_canon_sha256":"9c38376dae328d953db829e2fbe2823db21db304d797e052bb366373654a05c6"},"schema_version":"1.0","source":{"id":"2008.06857","kind":"arxiv","version":1}},"canonical_sha256":"0eee072b41bfbf5108af0f01e57bb3101f9add45745f527f6bab887b5cbffb03","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0eee072b41bfbf5108af0f01e57bb3101f9add45745f527f6bab887b5cbffb03","first_computed_at":"2026-07-05T02:05:42.513355Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:05:42.513355Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RGn/ttpc+KIv9op8nq3KhkG90oFdtoNKX7LeuLXuzID55LCkAUOfBj61gfAs9ce8E2BPbtKhem1BhnABOx70BQ==","signature_status":"signed_v1","signed_at":"2026-07-05T02:05:42.513728Z","signed_message":"canonical_sha256_bytes"},"source_id":"2008.06857","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5aead43186976f0b01509f9300187cd091fc9e91e203f70874e74d9dda9d94fe","sha256:2d9260c3b4d94a3fedd1ab54e7d1fca61c67991b3667babc2c6bc7fdb8d4ae5a"],"state_sha256":"21121c7604a4efd87a25583c41a3c6d90da0563fef7b80a48ea587427a113d2c"}
