Here we report the opposite behavior, a substantial enhancement of $T_c$ with decreasing thickness, in 2D crystalline superconductor 2H-TaS$_2$. Remarkably, in the monolayer limit, $T_c$ increases to 3.4 K compared to 0.8 K in the bulk. Accompanying this trend in superconductivity, we observe suppression of the charge-density wave (CDW) transition with decreasing thickness. To explain these trends, we perform electronic structure calculations showing that a reduction of the CDW amplitude ","authors_text":"Efr\\'en Navarro-Moratalla, Efthimios Kaxiras, Jonathan Ruhman, Kenji Watanabe, Pablo Jarillo-Herrero, Shiang Fang, Takashi Taniguchi, Valla Fatemi, Yafang Yang","cross_cats":["cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2017-10-31T19:54:17Z","title":"Enhanced Superconductivity and Suppression of Charge-density Wave Order in 2H-TaS$_2$ in the Two-dimensional Limit"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.00079","kind":"arxiv","version":2},"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":"sha256:54105a029fe3ae861e8d7be1d8b5b4b6181e83d23fedc23316e11c85303b36b1","target":"record","created_at":"2026-05-18T00:10:03Z","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":"85d47518afc21862f1a1f8b181d7a8331689197d0bbd54ab25adcff322789ebe","cross_cats_sorted":["cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2017-10-31T19:54:17Z","title_canon_sha256":"426390791a12297b33a0d750e063315cedd38b0eb403659d5c6c7d110a8e5a5a"},"schema_version":"1.0","source":{"id":"1711.00079","kind":"arxiv","version":2}},"canonical_sha256":"ddbd491877d1cd7d5511b60ac52c968811ec8e939c7dde70072b2e9e91488eb8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ddbd491877d1cd7d5511b60ac52c968811ec8e939c7dde70072b2e9e91488eb8","first_computed_at":"2026-05-18T00:10:03.786032Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:10:03.786032Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1gtht62GeAqmwpwZxG7Jj/8gQGrVNyOKyHuNZbn/HPAhpUle/KQau7evu3ofhj7uzqkoDLqHOZpXiyojjuStBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:10:03.786814Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.00079","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:54105a029fe3ae861e8d7be1d8b5b4b6181e83d23fedc23316e11c85303b36b1","sha256:0b8c8a35658e8dd1be33fb9f39207bbb982a8d41d10b4eb321b03688b758e450"],"state_sha256":"27b63e2b0ae240fa39bd3810a7490cb25651512064dada16b3952b58711fe73e"}
