Clean interface exists between graphene and Al-terminated (or hydroxylated) Al2O3 and the valence band offsets for these systems are large enough to create injection barrier. Remarkably, a band gap of {\\guillemotright} 180 meV can be induced in graphene layer adsorbed on Al-terminated surface, which could realize large ON/OFF ratio and high carrier mobility in graphene transistors without additional band gap engineering and significant redu","authors_text":"Bing Huang, Qiang Xu, Su-Huai Wei","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2011-10-21T22:47:38Z","title":"Theoretical Study of Corundum as an Ideal Gate Dielectric Material for Graphene Transistors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1110.4923","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":"sha256:6e036726316ee9487419bf5a34bf18ba6f83ec4d52f563c1457f4fc8bc765b7e","target":"record","created_at":"2026-05-18T02:00:06Z","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":"88ce5fd96d88d88f7026dbefef77d18fec7e1cb4c4e2bceb0ee94101da55f4b5","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2011-10-21T22:47:38Z","title_canon_sha256":"29cc367064685768cd891740edcd2ff4d5a3973c99927d09b342d8c3dbe59667"},"schema_version":"1.0","source":{"id":"1110.4923","kind":"arxiv","version":1}},"canonical_sha256":"d1a78ea44707584442e76a4b866d074d68be0dd9814f879bdb1316f352d20f30","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d1a78ea44707584442e76a4b866d074d68be0dd9814f879bdb1316f352d20f30","first_computed_at":"2026-05-18T02:00:06.976461Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:00:06.976461Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7Any1eF5wsaVmyzpokL1xcDpP8dTO3XK6/VjaxNyxDw2B27DtICT4MF/EcUWPt4QNmNBGT0w7APdmNmZsVLeDA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:00:06.976993Z","signed_message":"canonical_sha256_bytes"},"source_id":"1110.4923","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6e036726316ee9487419bf5a34bf18ba6f83ec4d52f563c1457f4fc8bc765b7e","sha256:2f08ebcd5e8fa396b57a561034a17bcfac22bbd5473b4a04962f90ffbb7a3b55"],"state_sha256":"274ab48814162e57aecd53b83d2c1e7b32ee9ac4497380353b13acf85a3668f0"}
