At a growth pressure of 0.04 mbar the interface is metallic, with a carrier density of the order of $10^{13}$ cm$^{-2}$ at 3 K. By increasing the growth pressure, we observe an increase of the out-of-plane lattice constants of the LaAlO$_3$ films while the in-plane lattice constants do not change. Also, the low-temperature sheet resistance increases with increasing growth pressure, leading to an insulating interface when the growth pressure reaches 0.10 mbar.","authors_text":"Chunhai Yin, Dileep Krishnan, Jan Aarts, Jo Verbeeck, Nicolas Gauquelin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-11-02T16:01:49Z","title":"Influence of stoichiometry on interfacial conductance in LaAlO$_3$/SrTiO$_3$ grown by 90$^o$ off-axis sputtering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.00953","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:db250a8bf38ff32a1a5b2e9fd7d703ab9d098b25fc4d09dd91e47f860038012d","target":"record","created_at":"2026-05-18T00:01:41Z","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":"f68b779691bd784b571b4cfb5e5e4844f11bfbf16b514276648ee7d445cf1d2e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2018-11-02T16:01:49Z","title_canon_sha256":"62c639f1f760d2c4dca6a04bd5c24400a09d08696da55a1375997a47930408d4"},"schema_version":"1.0","source":{"id":"1811.00953","kind":"arxiv","version":1}},"canonical_sha256":"2127a3f2bd997bc08b3ff4a62c8d09e744098b179351e6273dcbd147be179cb6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2127a3f2bd997bc08b3ff4a62c8d09e744098b179351e6273dcbd147be179cb6","first_computed_at":"2026-05-18T00:01:41.626353Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:41.626353Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gKArAL8QeqjNLdZBbu9XLD91DY5LBcxhI5dX/0tB0NKk4l5MNMjgjCaQkytHyZjC5+tgzxtGfKbMAQhjtM3rAg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:41.626990Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.00953","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:db250a8bf38ff32a1a5b2e9fd7d703ab9d098b25fc4d09dd91e47f860038012d","sha256:d71e48cbf028111a49fab099c6bb6b00c22acbcae4e9db718833d37c0bb96c59"],"state_sha256":"01570097a0fb434c576a35ee9f763097480defc7fbcf21a67e4db850c0553c09"}
