Systematic measurements in an ultrahigh vacuum nanoprobe system show that the oscillation frequency increases with the bias current and/or with decreasing device dimension. In contrast to most VO2-based oscillators reported to date, which are electrically triggered, current-induced Joule heating in the Pt overlayer is found to play a dominant role in the generation of oscillation in Pt","authors_text":"Hidekazu Tanaka, Jianwei Chai, Long Qi, Shijie Wang, Yanjun Xu, Yihong Wu, Ying Wang, Yumeng Yang","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2015-02-02T11:22:38Z","title":"Electrical Oscillation in Pt/VO2 Bilayer Strips"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.00442","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":"sha256:746187ebd403430a5097daee5b3c43ae0a33dde9cc4d9bcebbc2df99452de379","target":"record","created_at":"2026-05-18T01:41:05Z","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":"774eb4119151dd1cf90a3425f211e286f37d0f85384a2cb9f6ef6a62ab19b5ac","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2015-02-02T11:22:38Z","title_canon_sha256":"76c1435ae0d38d6daf2d690d6f3fe320c6067f732365871d916211c0108357a9"},"schema_version":"1.0","source":{"id":"1502.00442","kind":"arxiv","version":1}},"canonical_sha256":"9449bde9b647f4f2453ed827814a5a9c8c5aa8298cf385c14bc02f2584c7f5cc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9449bde9b647f4f2453ed827814a5a9c8c5aa8298cf385c14bc02f2584c7f5cc","first_computed_at":"2026-05-18T01:41:05.421277Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:41:05.421277Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QmPwGaIRN8qcqJPBbafcTUffRq8ZKUOIh72y7VqcFNMjcYLPYplmP9TB+1JMD3O057waeSGT4yVS+HtXrGxJBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:41:05.421924Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.00442","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:746187ebd403430a5097daee5b3c43ae0a33dde9cc4d9bcebbc2df99452de379","sha256:4b27aecbd5d5d0a9fa7a826dbfc5f9b183a5a60a802859c4e146f530eff72f86"],"state_sha256":"c1d5f90d2aca124ab10e59ea43172e460e9f2199a7e997d9d96d0feb56070c7e"}
