The results indicate that although Klein band-to-band tunneling is significant for sub-100nm graphene FET, it is possible to achieve a good transconductance and ballistic on-off ratio larger than 3 even at a channel length of 20nm. At a channel length of 20nm, the intrinsic cut-off frequency remains at a couple of THz for various gate insulator thickness values, but a thin gate insulator is necessary for a good transconductanc","authors_text":"Jing Guo, Jyotsna Chauhan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2011-02-07T22:28:08Z","title":"Assessment of High-Frequency Performance Limits of Graphene Field-Effect Transistors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1102.1457","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":"sha256:2655438c60bbbbc19100d2683a92da364bd670044d3aebe396698b7553a12782","target":"record","created_at":"2026-05-18T04:29:53Z","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":"0a3f617cf83baa180526d32f2b622f47fa87e9241536eeff41c46e11da62e753","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2011-02-07T22:28:08Z","title_canon_sha256":"1753d568d64630382db22b541eaf160779cdda8319e0810be769454d41df350c"},"schema_version":"1.0","source":{"id":"1102.1457","kind":"arxiv","version":1}},"canonical_sha256":"5f41db9552bd9cd965917eebf3b835f2074e483f4eb375e88cb6af119f41c58a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5f41db9552bd9cd965917eebf3b835f2074e483f4eb375e88cb6af119f41c58a","first_computed_at":"2026-05-18T04:29:53.188042Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:29:53.188042Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IZk1ijT4dVpIILBFcIHAw/c1K++zpaD+xKnOyzRSNG6KYg62TxtSK6oOGjyj2whlKaIe+uugtlVpz1bkR6oDDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:29:53.188709Z","signed_message":"canonical_sha256_bytes"},"source_id":"1102.1457","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2655438c60bbbbc19100d2683a92da364bd670044d3aebe396698b7553a12782","sha256:d48919db3bd6d500f244842fbb0406d95e809f33fd13ad083b9dc2c1dfb6ac7f"],"state_sha256":"35fa38e5bc8dcd7a5836bf8a255adbdb3f7db179c13e11b49a2042ff8236987e"}
