A stepped dielectric top gate creates a spatially modulated electric field, which opens the band gap in the graphene and produces an insulating region at the p-n interface. A current-voltage relationship exhibiting differential resistance peak at forward bias stems from the tunneling current through the insulating region at the p-n interface. The tunneling current reflects singularities in the density of states modified by the electric field. This work suggests that the effect of carrier charge tuning by external electr","authors_text":"Akinobu Kanda, Hidefumi Hiura, Hisao Miyazaki, Kazuhito Tsukagoshi, Michael Lee, Song-Lin Li","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2011-11-15T04:27:20Z","title":"Observation of Tunneling Current in Semiconducting Graphene p-n Junctions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1111.3428","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":"sha256:5c87e88e8973506a3620b77b8315a50e46d9589535c365844f428b91f82f2d7a","target":"record","created_at":"2026-05-18T04:06:09Z","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":"89238a9e8446688341dbf8df3038ef7bb5acba6de242ae97de3bfe53b35a9a91","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2011-11-15T04:27:20Z","title_canon_sha256":"5fe2b9351cb853760d93a2c0b2c9a6606905f706c918dea88d7b59626903fc78"},"schema_version":"1.0","source":{"id":"1111.3428","kind":"arxiv","version":1}},"canonical_sha256":"71843ed00f71354e81206a4cb5c23c8a0c125ae7d7f48625e54d1b26ea0b6eee","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"71843ed00f71354e81206a4cb5c23c8a0c125ae7d7f48625e54d1b26ea0b6eee","first_computed_at":"2026-05-18T04:06:09.280151Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:06:09.280151Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DAg0xCYi4sO6zc62X6gK1KblIudQf8r0YSG4qpsNWMhOBLoqE/mxEWdcsXn+FcNrF3NJtmTyaaF/kTYGcw+5Dg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:06:09.280646Z","signed_message":"canonical_sha256_bytes"},"source_id":"1111.3428","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5c87e88e8973506a3620b77b8315a50e46d9589535c365844f428b91f82f2d7a","sha256:787a67a80607d4b058ecdf8015b5c0ef219c47fe907789e08beddbe2a3517244"],"state_sha256":"08237f384154abc042931f2f89abdf75506c44c79fb44a70a3a2e8db270b310d"}
