With their sixfold symmetry and fractal-like shape, the crystals resemble snowflakes. The evolution of the dendritic growth features is investigated for different growth conditions and surface diffusion is found to be the growth-limiting step responsible for the formation of dendrites. The electronic properties of the dendritic crystals are examined down to sub-Kelvin temperatures, showing a mobility of up to 6300 cm$^2$V$^{-1}$s$^{-1}$ and quantum H","authors_text":"Dan Vatnik, Eric Whiteway, Mathieu Massicotte, Michael HILKE, Victor Yu","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2013-01-29T19:37:35Z","title":"Quantum Hall Effect in Fractal Graphene: Growth and Properties of Graphlocons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.7033","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":"sha256:9c839d15bfb3a45341859e38077d82ab1fa229a25a4ef6dce47ee572e33e244c","target":"record","created_at":"2026-05-18T03:35:02Z","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":"74f8fc9b5bcd9ffff83d1cfa7ac2c4fe8409f7fe2bbdef9322529b0d1bd26f5d","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2013-01-29T19:37:35Z","title_canon_sha256":"644b3e10221aaf943a230c4e6e869e3537369b832b473e1e82f2b6350047361b"},"schema_version":"1.0","source":{"id":"1301.7033","kind":"arxiv","version":1}},"canonical_sha256":"1e7eba5ca551fbeda3954b31cdd0498c48f42ec72425407d2630b93e142b12a2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1e7eba5ca551fbeda3954b31cdd0498c48f42ec72425407d2630b93e142b12a2","first_computed_at":"2026-05-18T03:35:02.837833Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:35:02.837833Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zn1qrPexxGz1clMmxMLjoN8qwhs72wEq/6rGDvkpugDor4dphJDkGY4McZor2CknUZ3hi6xTZ/p9Vkv0V9bLBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:35:02.838590Z","signed_message":"canonical_sha256_bytes"},"source_id":"1301.7033","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9c839d15bfb3a45341859e38077d82ab1fa229a25a4ef6dce47ee572e33e244c","sha256:598e138f03f9e6cf5e3eecc06a075c65d48cb24edf64ad6f7410afc62ffca1b6"],"state_sha256":"4d26d69ef17ec377593d9865050c1e01e13178fef12af597da4194f256eb2c99"}
