A record high mobility of 83 cm2/Vs (337 cm2/Vs) is reached at room temperature (low temperature) for monolayer WS2. A theoretical model for electron transport is also developed.","authors_text":"Baigeng Wang, Gang Zhang, Haiyan Nan, Junzhuan Wang, Run Xin, Tangsheng Chen, Xiaoxu Wei, Xinran Wang, Yang Cui, Yiming Pan, Yi Shi, Yong-Wei Zhang, Yun Wu, Zhenhua Ni, Zhihao Yu, Zhun-Yong Ong","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2015-10-03T14:07:26Z","title":"High-Performance Monolayer WS2 Field-effect Transistors on High-k Dielectrics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1510.00826","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":"sha256:672ff8965ba5377001c5bcb7ed0b4aadd26e5b0b5410f4b4fc761fbf2d939852","target":"record","created_at":"2026-05-18T01:31:05Z","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":"a5a1cdd1fe6072303aeb18f5d71ded02cae27a8be8b97876f10e16ac742ef2f7","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2015-10-03T14:07:26Z","title_canon_sha256":"32131d44ed09cd734b5fee0be6942f4ea658f2ffd49e9c86ff32f598772809ed"},"schema_version":"1.0","source":{"id":"1510.00826","kind":"arxiv","version":1}},"canonical_sha256":"eb865b1394a4d7b2b7f8414549d979712b357d74df527568210c7f97610cc1fa","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eb865b1394a4d7b2b7f8414549d979712b357d74df527568210c7f97610cc1fa","first_computed_at":"2026-05-18T01:31:05.526040Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:31:05.526040Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eM2uMi0dIQNCcmLlut/VaxQkRDIQbndF9XUisrcCXP7tUD7QW2JFKrv6/She3wEmPJVGhGKOUP80n0K4wKjcBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:31:05.526739Z","signed_message":"canonical_sha256_bytes"},"source_id":"1510.00826","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:672ff8965ba5377001c5bcb7ed0b4aadd26e5b0b5410f4b4fc761fbf2d939852","sha256:72e54f5b092232f7d556f314658d33c2da98bb33ecf9736ed38c424ce6845a36"],"state_sha256":"d328f02e2332ee5e6e038e09b4611976d68bfee31dd9a70831d31867ae9da909"}
