We find that drag occurs when the bulk of graphene is conducting, but is strongly suppressed in the quantum Hall regime when magnetic field confines conducting electrons to the edges of graphene and far from the nanotube. Out-of-equilibrium and non-linear drag measurements show intriguing interplay between 1D and 2D conductors. These hybrid electronic devices of novel geometry could lead to potential applications for Van der Waals elec","authors_text":"Austin Cheng, Jean-Damien Pillet, Kenji Watanabe, Philip Kim, Takashi Taniguchi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2016-12-18T21:12:46Z","title":"Coulomb drag between carbon nanotube and graphene"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1612.05992","kind":"arxiv","version":3},"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":"sha256:54b205b31e74d7d863fd5e0777eff9db64663b8a2e66f8d53fafaffdb514431e","target":"record","created_at":"2026-05-18T00:32:36Z","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":"298a142945889b2a2dedb0d0edd0fbd123e74af4730db52f3f4c1221d1bdcaec","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2016-12-18T21:12:46Z","title_canon_sha256":"b285ed03043d96fbe81e48580ec2b73afb9609385b6bd0bdbdf9650e59bcd2fa"},"schema_version":"1.0","source":{"id":"1612.05992","kind":"arxiv","version":3}},"canonical_sha256":"38fc0030fa94e2570fd15447ba4af64e7b478251672a318aa723ac951e39178e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"38fc0030fa94e2570fd15447ba4af64e7b478251672a318aa723ac951e39178e","first_computed_at":"2026-05-18T00:32:36.352691Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:32:36.352691Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0JRTg5Zr/sLIkk0cJJqLhzLaIiTk0m6DWpJw/7WHOVeNo2ZauPv+R65e6asH7rrg/UhEe5QgOXgNdLS8McjZBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:32:36.353408Z","signed_message":"canonical_sha256_bytes"},"source_id":"1612.05992","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:54b205b31e74d7d863fd5e0777eff9db64663b8a2e66f8d53fafaffdb514431e","sha256:1c2849c3a7e608225cfc18ee4af971512cd002e5bf5e04bbfdf5409dd612e6b4"],"state_sha256":"d4ab64bb8baa3446fbe76dda43bb29408feb0c1b230c2e68dbaccbd4b0944bd1"}
