At low temperatures, the surface of semiconductors is typically amorphized by the ion beam. Above a material dependent dynamic recrystallization temperature however, the surface remains crystalline and ion beam irradiation produces regular arrays of faceted ripples on III-V semiconductors. This provides a powerful single-step technique for the production of nanostructures on a large area. On $(001)$ surfaces these ripples are parallel to the $[1\\bar{1}0]$ direction w","authors_text":"Martin Engler, Stefan Facsko, Tom\\'a\\v{s} \\v{S}kere\\v{n}","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2016-11-21T15:32:30Z","title":"Nano patterns self-aligned to Ga dimer rows on GaAs surfaces"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.06836","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:b8442af549c1467cd99fbe62d6df70560c1f77f04d470dd7b16c317f12329932","target":"record","created_at":"2026-05-18T00:57:32Z","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":"d3371cc6b25eb26505dae040b2c98118cb92419405ba47f659dcda93b9b5a20c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2016-11-21T15:32:30Z","title_canon_sha256":"c0d9222a62128d8df9c9e1cb9f97f029f0277b91073a3ecee9053d55cfaad36b"},"schema_version":"1.0","source":{"id":"1611.06836","kind":"arxiv","version":1}},"canonical_sha256":"35b8907526fa52c133902891e63759dedc3ad3847e36049f2127e2138ba37c10","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"35b8907526fa52c133902891e63759dedc3ad3847e36049f2127e2138ba37c10","first_computed_at":"2026-05-18T00:57:32.752573Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:57:32.752573Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eNUV6Y0g5lF4GfxwyW/bKlqQjEV0UMYZYMNDZ2itpcfiGCFJLpjRDfUjbjRiGPoWZYuvzXNEfGOls8MunixeBA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:57:32.753074Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.06836","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b8442af549c1467cd99fbe62d6df70560c1f77f04d470dd7b16c317f12329932","sha256:06ad5d686467a3e707df9fc59abfbcdb1d6bdfe700dc17cc90071f6df8486a73"],"state_sha256":"07b48ff947bbe2d1bf46cdb5d59fc74913c04c42faf2cabeeb109c53d5646478"}
