The optimized rapid etch process provides results in improving etching quality with a 0.26-nm roughness of the anode recessed surface. By using the high work function metal Pt as the Schottky electrode, a low Von of 0.71 V is obtained with a high uniformity of 0.023 V for 40 devices. Supported by the flat anode recess surface and related field plate design, the SBD device with the anode-cathode spacing of 15 um show the Ron,sp of 1.53 mOhm.cm2 only, t","authors_text":"Bin Liu, Cheng Ge, Haocheng Peng, Jing Zhou, Menghan Liu, Peng Chen, Rong Zhang, Ru Xu, Yimeng Li, Youdou Zheng, Yunfei Yang, Zili Xie","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2020-07-07T01:45:53Z","title":"2.5-kV AlGaN/GaN Schottky Barrier Diode on Silicon Substrate with Recessed-anode Structure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2007.03163","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":"sha256:256d56d49abcb8204ac73d3360a456a300b990ce9ec6d96b7fd8508b8df1436a","target":"record","created_at":"2026-07-05T02:17:27Z","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":"c7427d3ecfbb498c9f4a34648f4500c72d978a0b460cce33fa118dd201cd73cb","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2020-07-07T01:45:53Z","title_canon_sha256":"3ce9be64f3ebea3325858cbf04b27dd8da20989096b6081bb3a1967c7b1aa020"},"schema_version":"1.0","source":{"id":"2007.03163","kind":"arxiv","version":1}},"canonical_sha256":"8b628db42a099f2c694a3678621083bd51b62c43022f2342e68838177fd9d5c8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8b628db42a099f2c694a3678621083bd51b62c43022f2342e68838177fd9d5c8","first_computed_at":"2026-07-05T02:17:27.729631Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:17:27.729631Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zhFmA0uB3FOMxB8Zc52ZN2BYuzAy16AWylbdXTFtgNzV5DGwyNHMVYGdZjBuIbclnR3LyJEqEpGColPXtWTiDA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:17:27.730180Z","signed_message":"canonical_sha256_bytes"},"source_id":"2007.03163","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:256d56d49abcb8204ac73d3360a456a300b990ce9ec6d96b7fd8508b8df1436a","sha256:129b06703e15e17465de203e796c95ee5dfbbb8553940059f22e813bef13f7cc"],"state_sha256":"1790d9c550864a23e9eb7897d1e42b60f2ecd613eaa62b12e3784c4a21833977"}
