Despite this dramatic variation, a robust trend is that within each family, the double-layer compound always has higher Tc,max than the single-layer counterpart. Here we use scanning tunneling microscopy to investigate the electronic structure of four cuprate parent compounds belonging to two different families. We find that within each family, the double layer compound has a mu","authors_text":"Changqing Jin, Cheng Hu, Cun Ye, Jianfa Zhao, Peng Cai, Runze Yu, Wei Ruan, Xingjiang Zhou, Xintong Li, Yayu Wang, Yingying Peng, Zheng-Yu Weng, Zhenqi Hao","cross_cats":["cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2017-01-16T06:50:09Z","title":"Relationship between the parent charge transfer gap and maximum transition temperature in cuprates"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.04190","kind":"arxiv","version":2},"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":"sha256:67d038c8140c11148f6063e7f16c1dac0e02827fa787e25657ff2b073f1e62f4","target":"record","created_at":"2026-05-18T00:52:30Z","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":"e086e9166ca8b88e68162ec1323f4d32633b6a736d06628b7887d76731fa0776","cross_cats_sorted":["cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2017-01-16T06:50:09Z","title_canon_sha256":"64fc11fbe16257f9ccede54b148dc30444eff91be912710aa519c451673ea728"},"schema_version":"1.0","source":{"id":"1701.04190","kind":"arxiv","version":2}},"canonical_sha256":"46ffcdd10bea1962519b21f06fec6f4e6a348e09e66d8f432ccfc23f61b0b18e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"46ffcdd10bea1962519b21f06fec6f4e6a348e09e66d8f432ccfc23f61b0b18e","first_computed_at":"2026-05-18T00:52:30.604568Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:52:30.604568Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"SyyZ5RwfP0ZocmWuyCJ1wS/9u9r79yyN5y2U2afFPD3lMC4lmuXWUl103TGzcbSbPjm46RAAuD8cLwtYFfZODw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:52:30.605163Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.04190","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:67d038c8140c11148f6063e7f16c1dac0e02827fa787e25657ff2b073f1e62f4","sha256:18d920501c85b0317f74a2ccfa721e2b799a6eb0d1b733d80f12a2f9c28f3946"],"state_sha256":"3bba7385177772524e9d775e7466de2bdef076950ef2928a3c9f479a548f166f"}
