However, the beneficial effect of La on the endurance of polycrystalline films may be accompanied by degradation of the retention. We have investigated the endurance - retention dilemma in La-doped epitaxial films. Compared to undoped epitaxial films, large values of polarization are obtained in a wider thickness range, whereas the coercive fields are similar, and the leakage current is substantially reduced. Compared to polycrystalline La-doped films, epitaxial La-doped films show more fatigue but there is no","authors_text":"Florencio Sanchez, Guillaume Saint-Girons, Ignasi Fina, Raul Solanas, Romain Bachelet, Tingfeng Song","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2020-10-27T09:31:12Z","title":"Epitaxial Ferroelectric La-doped Hf0.5Zr0.5O2 Thin Films"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2010.14154","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:a1f3fb3fde95a8ebecec6680dbb94d79c70b1c2eba18e97a29fb9b5f0e886a50","target":"record","created_at":"2026-07-05T01:47:15Z","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":"99d34aa8da549885a3f6a416d305eccfbcde7e0db1cf4b1aa1e3b7c6dfa2296e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2020-10-27T09:31:12Z","title_canon_sha256":"e7d8e29b2c2ca37507e3e5936e72356837f509ce85a6d9fae148f53c19516326"},"schema_version":"1.0","source":{"id":"2010.14154","kind":"arxiv","version":2}},"canonical_sha256":"b24eb94eee9042ff9d5a32b4c79f22d9fa5e98b17a05c4b5a15b5ae40a6869ef","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b24eb94eee9042ff9d5a32b4c79f22d9fa5e98b17a05c4b5a15b5ae40a6869ef","first_computed_at":"2026-07-05T01:47:15.948564Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:47:15.948564Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bKtrz2ueS4F8e7j4wd2AAEb8jrrVy+FO+W4eVQEt71f/NhJ+VwjOiCMBvDCVIYZtF+xX7ZJUo1HpkGbg48ajAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T01:47:15.948965Z","signed_message":"canonical_sha256_bytes"},"source_id":"2010.14154","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a1f3fb3fde95a8ebecec6680dbb94d79c70b1c2eba18e97a29fb9b5f0e886a50","sha256:9100ea17625ecfcd7c4c2c6c882109802970b7da1fbb40008b8e067d2109940f"],"state_sha256":"0d1978d20dfba53c81db6baa0759c6df892191a8cf0192fd1849cf9a02d09a44"}
