When a semiconductor sample exhibiting quantum Hall effect is placed inside the haloscope, two-dimensional ( 2D ) electrons absorb the axion induced radiation. The power of the absorbed radiations is large enough to be detectable. We consider a GaAs sample with surface area $S=10\\,\\mathrm{cm}^2$ and small thickness $\\ll 1\\mathrm{mm}$. The power is $P_s \\simeq 5.2 \\times 10^{-24}W\\Big(\\frac{g_{\\gamma}}{0.36}\\Big)^2 \\Big(\\frac{B_t}{15T}\\Big)^2\\Big(\\frac{V}{7.2\\, \\mathrm{l}}\\Big)\\Big(\\frac"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.19888","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2607.19888/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"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"}
