The NDR originates from an interplay of orbital spatial asymmetry and strong electron-electron interaction, which causes the molecule to become trapped in a non-conducting state above a voltage threshold. We show how the desired asymmetry can be selectively introduced in individual orbitals in e.g., OPE-type molecules by functionalization with a suitable side group, which is in lin","authors_text":"Karsten Flensberg, Martin Leijnse, Mogens Br{\\o}ndsted Nielsen, Per Hedeg{\\aa}rd, Wei Sun","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2010-12-17T11:36:45Z","title":"Interaction-induced negative differential resistance in asymmetric molecular junctions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1012.3856","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":"sha256:8c788219137668996339bcf31e949541b8e5503159bf71c3abc39f3513e0edf3","target":"record","created_at":"2026-05-18T03:36:56Z","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":"9e7f9cbfe2701bc309be8a677c35e0e0e3d2c22a29d3635a081cbd339ca79fa0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2010-12-17T11:36:45Z","title_canon_sha256":"7eadc124c63c1a13ed9cda6bb1de8f87a32fbcc5524abe55ec0742ccbad84503"},"schema_version":"1.0","source":{"id":"1012.3856","kind":"arxiv","version":1}},"canonical_sha256":"de34ce154b2330fc7d9ad936fd8457c1de7372af3cd4eb7ab598cd0c6f530c54","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"de34ce154b2330fc7d9ad936fd8457c1de7372af3cd4eb7ab598cd0c6f530c54","first_computed_at":"2026-05-18T03:36:56.854416Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:36:56.854416Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"d+zFMVLWvBY+T/0xX3vMdzdCWVs5ySJg1izu2Lp1QZYBAR6ONBvCxFc1K92ym+WmEbWQA0fQH4qy0ooPHsB1Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:36:56.854913Z","signed_message":"canonical_sha256_bytes"},"source_id":"1012.3856","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8c788219137668996339bcf31e949541b8e5503159bf71c3abc39f3513e0edf3","sha256:2292a16b645472d95d38479ccafe9a5c6cc4bebe9aa7644339b257c5ebe9564b"],"state_sha256":"bd4f48e5768e3c07642fc9a3a430a87d690eb9b69eea6316043d2aefbc544390"}
