Avoiding the production of Cu2Se, which has a higher melting point than that of Bi2Se3, and quenching Cu-Bi-Se mixtures at the liquid phase are keys to obtaining good superconducting samples in a reproducible manner.","authors_text":"Atsutaka Maeda, Ryusuke Kondo, Taiki Yoshinaka, Yoshinori Imai","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2013-03-15T14:41:58Z","title":"Reproducible synthetic method for the topological superconductor CuxBi2Se3"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1303.3786","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":"sha256:680a33e71fd8510830abe4010933fe5938a0e33eb1cff6a291735ae6e32cce7b","target":"record","created_at":"2026-05-18T01:51:06Z","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":"254d06df8138a42d1893bb027e8b57ee33057c2a4bdef2f2be2f99771bb348fd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2013-03-15T14:41:58Z","title_canon_sha256":"3c6be5a64588ee0a22016cc60032e38311470a0424dca34d566b68b33e1a44e6"},"schema_version":"1.0","source":{"id":"1303.3786","kind":"arxiv","version":1}},"canonical_sha256":"f149d6af9965966336e04cc47aea8701c9cac75134291dedef2fede5e0ecf975","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f149d6af9965966336e04cc47aea8701c9cac75134291dedef2fede5e0ecf975","first_computed_at":"2026-05-18T01:51:06.833724Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:51:06.833724Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"mNtKKCEk4NuYREy1TTTijHGThUAnd/vILpJBE6lHj7Wyi8H8wNW/LD6TCkIGTHCwc83lY9EBmSUGNkUfngJHAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:51:06.834274Z","signed_message":"canonical_sha256_bytes"},"source_id":"1303.3786","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:680a33e71fd8510830abe4010933fe5938a0e33eb1cff6a291735ae6e32cce7b","sha256:c6204ef8ab182737cc8aad9dcd003d5633628fd7e84711173ce4e920de0fb376"],"state_sha256":"7615db182f13f73abcba1f4a7c856c53c50b8cbfb6a2450f3c129c8783a1018c"}
