In this letter we show, through systematic experiments, a chemical vapor sensor based on the measurement of low frequency resistance fluctuations of single layer graphene field-effect-transistor (SLG-FET) devices. The sensor has extremely high sensitivity, very high specificity, high fidelity and fast response times. The performance of the device using this scheme of measurement (which uses resistance fluctuations as the detection parameter) is more than two orders of magnitude be","authors_text":"Aveek bid, Kazi Rafsanjani Amin","cross_cats":["physics.ins-det"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-11-19T15:44:13Z","title":"High performance sensors based on resistance fluctuations of single layer graphene transistors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.06213","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:fda35b65969074f291a5fcf1fffd5c70cd1ea8beb6d2584986e73e2f9a73338f","target":"record","created_at":"2026-05-18T01:26:26Z","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":"23376b1b6b1a8df2af9aa95d4d586e47ba1913a4a6e04fc90a3e716f8eb572af","cross_cats_sorted":["physics.ins-det"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-11-19T15:44:13Z","title_canon_sha256":"12154f482867c7f441da7a0de96fb9f48dc2efa2e3e77d4f5ea327a195a34a53"},"schema_version":"1.0","source":{"id":"1511.06213","kind":"arxiv","version":1}},"canonical_sha256":"7b591e303a6300382a80921ed68a0c05b501385e016c5084d5d5d2ae00a19e3c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7b591e303a6300382a80921ed68a0c05b501385e016c5084d5d5d2ae00a19e3c","first_computed_at":"2026-05-18T01:26:26.090440Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:26:26.090440Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ysF0OhT/yeAaQoFVAXyO/F7GhDYDnyo6LFlMcOZ0qONt51pBl+t8QOi7tQBm0zKvcIoCwz2vYf8QtjTnFAjUCw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:26:26.090833Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.06213","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fda35b65969074f291a5fcf1fffd5c70cd1ea8beb6d2584986e73e2f9a73338f","sha256:87e4514059769fcb7ed5a09dc1298f28ae97faa2287bf1cb4aa424928d3e25e0"],"state_sha256":"3576778fea9e0c870027f17cab814daccd7a217d34590e8aa7989da4e508ac67"}
