We construct bicrystalline graphene samples containing grain boundaries with symmetric tilt angles using the two-dimensional phase field crystal method and then relax the samples with MD. The corresponding Kapitza resistances are then computed using nonequilibrium MD simulations. We find that the Kapitza resistance depends strongly on the tilt angle and shows a clear correlation with the average density of defects in a given grain boundary, b","authors_text":"Ari Harju, Ken R Elder, Khatereh Azizi, Petri Hirvonen, S Mehdi Vaez Allaei, Tapio Ala-Nissila, Zheyong Fan","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2017-09-27T13:59:56Z","title":"Kapitza thermal resistance across individual grain boundaries in graphene"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.09529","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:f2f276b385994c18c251490316a96586c903b41055def8df4c42bc8f55e4800d","target":"record","created_at":"2026-05-18T00:34:11Z","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":"5a6563cc9261f8077e2db528633d9e7ee808f0710d1f1a9d4c4eb954a975f9fd","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2017-09-27T13:59:56Z","title_canon_sha256":"b9f927f81a6b87baf2d74f2bc5c88a2202ab86245aeddf812702ec8144b2d22a"},"schema_version":"1.0","source":{"id":"1709.09529","kind":"arxiv","version":1}},"canonical_sha256":"e25e1f3b3e02d4289af73f37ec9dfd146ea6c07516dc18ad360912fc273b7209","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e25e1f3b3e02d4289af73f37ec9dfd146ea6c07516dc18ad360912fc273b7209","first_computed_at":"2026-05-18T00:34:11.429907Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:11.429907Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"T+JxuNoiAM6l6JAflPs2lYvAaiK+tkb4X3peMcyEdGJ/TVDtKQuwUIlmq3fIe8whI2wnUCKe3WdB3nvRDl1GBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:11.430588Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.09529","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f2f276b385994c18c251490316a96586c903b41055def8df4c42bc8f55e4800d","sha256:72c391358457605e9b629b62f6a568dd728c6b5ddf23d3953d420fcc2fd84761"],"state_sha256":"14cd38db34f37312e5edbc38559348195ee7068fdf668402735e1ec4810bad47"}
