The intrinsic Curie temperature Tc of monolayer GeTe is as high as 570 K and can be raised quickly by applying a tensile strain. An out-of-plane electric field can effectively decrease the coercive field for the reversal of polarization, extending its potential for regulating the polar","authors_text":"Chang Liu, Wende Xiao, Wenhui Wan, Yugui Yao","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2017-05-25T02:42:17Z","title":"Promising Ferroelectricity in 2D Group IV Tellurides: a First-Principles Study"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.09029","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":"sha256:42583361d585f26d4c425ea5865adec20f75f8b3f7055fe8c068687661e3b079","target":"record","created_at":"2026-05-18T00:34:04Z","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":"150870bd55e8b5e14a50d140481912b4b5c9cab8b1278d5b004675297c592678","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2017-05-25T02:42:17Z","title_canon_sha256":"e2304b9edd04a7499b1507cbb08ff926e00b8d7b1fb567f65d32346d6200c994"},"schema_version":"1.0","source":{"id":"1705.09029","kind":"arxiv","version":2}},"canonical_sha256":"0c4fed347ecbe12e8ba33a3347a28a61be73f59c8f8f4dd358bbc6ad6425ff4a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0c4fed347ecbe12e8ba33a3347a28a61be73f59c8f8f4dd358bbc6ad6425ff4a","first_computed_at":"2026-05-18T00:34:04.758652Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:04.758652Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gFXBK7BgU7KZ/ah4nXs/017yYAidf6mnTyFcO/iwZqob8kMdJhrpQd3/8Y1QWe+GHwgakPk5XedDUFYkbZ3aCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:04.759237Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.09029","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:42583361d585f26d4c425ea5865adec20f75f8b3f7055fe8c068687661e3b079","sha256:707cc7976b7eaf97be132c9e52b287fdba49cee6807ae92191480a5cacf68a75"],"state_sha256":"f11ccb648e1f14023dfe40cae7ab2fb2f90e530bc356ae527c80f60e84c51f0d"}
