Their in-plane covalent bonding and dangling-bond-free surface allow them to assemble various van der Waals heterostructures (vdWHSs) with sharply atomic interfaces that are not limited by lattice matching and material compatibility. Interlayer coupling, as a ubiquitous phenomenon residing among 2D materials (2DMs) systems, controls a thin layer exfoliation process and the assembly of vdWHSs and behaves with a unique degr","authors_text":"Lijun Zhang, Xinjiang Wang, Yawen Li, Yuanhui Sun, Zhiming Shi","cross_cats":["physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-08-20T15:00:18Z","title":"Interlayer Coupling in Two-Dimensional Semiconductor Materials"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.06491","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":"sha256:5b1d1f0fcc372603259ebb4ad0e1db1ce85484d84959556b42bc2e856d0f4335","target":"record","created_at":"2026-05-18T00:06:56Z","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":"8070de2baaa12320151c13abf9ff7e4d07033a77a8743120fbde30cf9274b849","cross_cats_sorted":["physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-08-20T15:00:18Z","title_canon_sha256":"8cf56417aff2ebb79f7a0f8b3ab66caf75edc6992032fd64e960bd0ab6518668"},"schema_version":"1.0","source":{"id":"1808.06491","kind":"arxiv","version":1}},"canonical_sha256":"8ba5acfb1842a57cbfa9b23f268363225d53b47315adfda10b3826171ccf51ac","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8ba5acfb1842a57cbfa9b23f268363225d53b47315adfda10b3826171ccf51ac","first_computed_at":"2026-05-18T00:06:56.939001Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:56.939001Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"84FboYc1yjsr75mnniMDgVPXYWtwmG4o/2+7mTWdyfYEnKQLNqYNlR3fWOdusPMefmSJ95K/qQTZKW+2P42JBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:56.939634Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.06491","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5b1d1f0fcc372603259ebb4ad0e1db1ce85484d84959556b42bc2e856d0f4335","sha256:e9cba098f923aa3a37c9dc2bb980a6d261917bb8dd7562934269a313a13a2e09"],"state_sha256":"50dffbfe056a3129bbcfd4d88f085d84cea833e9478238c30786a45df48b7e84"}
