Here we investigate via first-principle techniques the formation and dynamics of small polarons on the reduced surface of titanium dioxide, an archetypal system for polarons, for a wide range of oxygen vacancy concentrations. We report how the essential features of polarons can be adequately accounted in terms of few quantities: the local structural and chemical environment,","authors_text":"Cesare Franchini, Martin Setvin, Michael Schmid, Michele Reticcioli, Ulrike Diebold","cross_cats":["physics.chem-ph","physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-05-04T16:46:47Z","title":"Formation and dynamics of small polarons on the rutile TiO$_2$(110) surface"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.01849","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":"sha256:06763a5dd5ba8c81eda03e6544aed24069f1b40f9e080732352e4b69a9697ca9","target":"record","created_at":"2026-05-18T00:09:59Z","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":"ecd6570b5f60f218aa55d9397dc7000500f0313d592eccffc4b6ea9d6f99800a","cross_cats_sorted":["physics.chem-ph","physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-05-04T16:46:47Z","title_canon_sha256":"bacfc5d4d7c0d77d77a6f28faa8fb677c8710d98708e6b01c15b5f2b3caa5428"},"schema_version":"1.0","source":{"id":"1805.01849","kind":"arxiv","version":1}},"canonical_sha256":"ae213ad1d6746a819fde6e41b4dd3c8fd65d8a8dc690f1b8606f453261e707c9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ae213ad1d6746a819fde6e41b4dd3c8fd65d8a8dc690f1b8606f453261e707c9","first_computed_at":"2026-05-18T00:09:59.432263Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:59.432263Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HL3TyW36Yik3egOY+0q9MGaO02JyON/AOLqRB/cjLnptYcy6OWImchx27AFmoCWab/LqxBLAki1VzHVbVUdvCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:59.432972Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.01849","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:06763a5dd5ba8c81eda03e6544aed24069f1b40f9e080732352e4b69a9697ca9","sha256:cbd34eeb463ae94b176b1233f2865aea178cd35949875ce9d4e1499050a3f303"],"state_sha256":"7ce05a9e5453425806441620ad2d5bc7ba70a562a22c2ab0fb7596b47eb6860f"}
