By proper interfaces designing, a large interface polarization emerges when the growth direction is chosen along {[}111{]}. Such an intrinsic polarized electrostatic field reduces band gap largely and invert the band structure finally, leading to emerge of the topological Dirac semimetal phase with a pair of Dirac nodes appearing along the (111) c","authors_text":"Dong Zhang, Jia-Ji Zhu, Jian-Peng Sun, Kai Chang","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2016-07-15T06:46:00Z","title":"Topological Dirac semimetal phases in InSb/$\\alpha$-Sn semiconductor superlattices"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.04391","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":"sha256:8a8792090c3cc50b3efad2361a5109897b79cc1d520a4bd6663a296b33c4b32a","target":"record","created_at":"2026-05-18T01:11:01Z","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":"09814e9be16573e1335ed3b6bfcaf36e8a422b3b40664556d0b57b3deb64eae5","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2016-07-15T06:46:00Z","title_canon_sha256":"3c776d7639338ece727bf645d0d77867a2cc939f2ecf29b36eeaf936f972ba87"},"schema_version":"1.0","source":{"id":"1607.04391","kind":"arxiv","version":1}},"canonical_sha256":"e6ba4639afe8e43c21ca8b6639ac6af110fee20e13eeba10c05e0fbd290e3ffc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e6ba4639afe8e43c21ca8b6639ac6af110fee20e13eeba10c05e0fbd290e3ffc","first_computed_at":"2026-05-18T01:11:01.343189Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:11:01.343189Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"aOSvkPnvJLeH5yLHxtaADm2dMVwZcRp9v3WSZMVDIbZz2AHrJgf6p74Y5adYqAMtc+WNbHq+WnnQPpub2/vLDw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:11:01.343894Z","signed_message":"canonical_sha256_bytes"},"source_id":"1607.04391","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8a8792090c3cc50b3efad2361a5109897b79cc1d520a4bd6663a296b33c4b32a","sha256:c4fdd014376b21b961aa8aae6ba9472d35cd900e407386ad7b36bf98112313da"],"state_sha256":"35178d05c22e45c8a1c11ede8c2170f281caf8a5bc073d152383827d7c00b10b"}
