In this study, we demonstrate three-dimensional (3D) visualization of dislocations in \\b{eta}-Ga2O3 using synchrotron-radiation X-ray topo-tomography under a two-beam Borrmann-effect condition in transmission X-ray topography. By rotating the sample about the diffraction vector and acquiring a series of topo-tomographic images at different rotation angles, the evolution of dislocation contrast is captured, providing intuitive, depth-re"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"This study represents the first demonstration of 3D dislocation reconstruction in beta-Ga2O3.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the observed evolution of dislocation contrast upon rotation about the diffraction vector directly corresponds to accurate depth-resolved 3D positions without significant projection artifacts or overlap ambiguities.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"First 3D reconstruction of dislocations in β-Ga₂O₃ via Borrmann-effect X-ray topo-tomography.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Rotating beta-Ga2O3 samples about the diffraction vector encodes depth positions of dislocations in X-ray images.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"14d1c525874db291b666fdcb25db3a4cb2c1a20bc1f69296052e4d964fde42b7"},"source":{"id":"2604.17826","kind":"arxiv","version":2},"verdict":{"id":"aa31da36-16e0-4da2-9fd6-87f7f5e1911e","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-10T04:46:01.013772Z","strongest_claim":"This study represents the first demonstration of 3D dislocation reconstruction in beta-Ga2O3.","one_line_summary":"First 3D reconstruction of dislocations in β-Ga₂O₃ via Borrmann-effect X-ray topo-tomography.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the observed evolution of dislocation contrast upon rotation about the diffraction vector directly corresponds to accurate depth-resolved 3D positions without significant projection artifacts or overlap ambiguities.","pith_extraction_headline":"Rotating beta-Ga2O3 samples about the diffraction vector encodes depth positions of dislocations in X-ray images."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.17826/integrity.json","findings":[],"available":true,"detectors_run":[{"name":"doi_compliance","ran_at":"2026-05-20T04:43:15.402753Z","status":"completed","version":"1.0.0","findings_count":0}],"snapshot_sha256":"406078a15d559c983d7e65b425b4268e9cecd5e115bc53ba48bf9cee11617745"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
