We have fabricated FeFET devices with different interlayers (SiO2 or SiON) and HfxZr1-xO2 materials (x=0.75, 0.6, 0.5), and directly extracted the charge trapping during endurance fatigue. We find that: 1) The introduction of the N element in the interlayer suppresses charge trapping and defect generation, and improves the endurance characteristics. 2) As the spontaneous polarization (Ps) of the HfxZr1-xO2 decr","authors_text":"Fengbin Tian, Hao Xu, Jiahui Duan, Jinjuan Xiang, Junshuai Chai, Kai Han, Shujing Zhao, Tianchun Ye, Tingting Li, Wenjuan Xiong, Wenwu Wang, Xiaolei Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2021-07-08T14:11:35Z","title":"Impact of Interlayer and Ferroelectric Materials on Charge Trapping during Endurance Fatigue of FeFET with TiN/HfxZr1-xO2/interlayer/Si (MFIS) Gate Structure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2107.03854","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":"sha256:115612f034d248698cdc6f70f69bcd5caec9f1f7b8b314a750b1bcadf25172c8","target":"record","created_at":"2026-07-05T03:45:36Z","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":"b2974ad7653f8fd680150c7de6f929fc63a178f1c8ee235a11a7d658eb1f0446","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2021-07-08T14:11:35Z","title_canon_sha256":"b18be43c8f65990634b072f4b4999e2cc22a417ae0c6eb008d51e8e0dc21d39e"},"schema_version":"1.0","source":{"id":"2107.03854","kind":"arxiv","version":1}},"canonical_sha256":"c9957d0eb66071f7de595dd68b7f2d9730bc7b7faf60114502e08a4fcf6aabbb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c9957d0eb66071f7de595dd68b7f2d9730bc7b7faf60114502e08a4fcf6aabbb","first_computed_at":"2026-07-05T03:45:36.939099Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:45:36.939099Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UPwE5BzKOerZY2etECrlNgLIPnTm6/w7EmgoNDg9QSbD0Wg4mbqoggURMt6gSJhBKr8U177GEk0wxNf4YXWUDg==","signature_status":"signed_v1","signed_at":"2026-07-05T03:45:36.939595Z","signed_message":"canonical_sha256_bytes"},"source_id":"2107.03854","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:115612f034d248698cdc6f70f69bcd5caec9f1f7b8b314a750b1bcadf25172c8","sha256:abbf2a7dd48a731d3a217c3c437aeec687e108bdff6d2abfd38b8b0f49930c33"],"state_sha256":"4ce1a9513b424d680f6fe3533cb827b988d23e3fcc2458b5b376e11d629dbc36"}
