In addition, a pair of screw-type TDs with opposite Burgers vectors, +1c, -1c, was observed in the transmission SR-XRT. These results demonstrate that the combined use of reflection and transmission SR-XRT provides a practical approach for complete determination of Burgers vectors in GaN substrates.","weakest_assumption":"The assumption that contrast size in reflection images, gb invisibility in transmission images, and kinematical linewidths uniquely and unambiguously determine all components of the Burgers vector without interference from other diffraction effects, overlapping defects, or sample-specific variations."}},"verdict_id":"5e77dfda-f429-4dba-9f57-69070b23ed5b"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0c11d4d9d668e8998f3082c87f739d2c1d566d6ed9792280b2bd0a8d9fcda67a","target":"record","created_at":"2026-05-20T00:01:40Z","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":"d115b8ebd1983229332af1af78612f7040b88d180257130e4326d5317e197428","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-04-06T03:45:42Z","title_canon_sha256":"20c53e89f6c6b0753867eb63c634d96667d3a5eb85eb689a941b2d6d7dcd25ab"},"schema_version":"1.0","source":{"id":"2604.04392","kind":"arxiv","version":3}},"canonical_sha256":"d43054fbd39a5ea29986dcd8b47a045dcd27845fc44d4d2a16d62e4b0e5255eb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d43054fbd39a5ea29986dcd8b47a045dcd27845fc44d4d2a16d62e4b0e5255eb","first_computed_at":"2026-05-20T00:01:40.858762Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:01:40.858762Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"b7VtzP8RE1w/bW/iiDPMSaH7OxHdRhhleTSb5K1z/p9/mpoLy0MKzcOiw6SgVZl0xGwMwFvIcWSqQ5JYUlylBQ==","signature_status":"signed_v1","signed_at":"2026-05-20T00:01:40.859556Z","signed_message":"canonical_sha256_bytes"},"source_id":"2604.04392","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0c11d4d9d668e8998f3082c87f739d2c1d566d6ed9792280b2bd0a8d9fcda67a","sha256:c0e5ff8503281b48984ebd087eac5e875163204c498742a050045ce819b14d05"],"state_sha256":"313bf9928b37c0502c5ab34d30f56e38a137694a3c86a94a68e564d5a063b17e"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"SQuvB9TtoQAnpKWO0O/8JyKIwcqpoqqedAkHMyCMJInZkup0KWZ6LQUejtGxMt/ORkCjKQWLP5DFivOcASXsAQ==","signed_message":"bundle_sha256_bytes","signed_at":"2026-05-27T16:37:55.214541Z","bundle_sha256":"e5e67cbc7b9365236db00af0dd976d855cdc9d0e3822da083e9292b3042de683"}}
