We found that the barrier $\\Delta$ strongly depends on the magnitude and character of the graphene's doping ($\\delta n$): it increases for hole doping ($\\delta n<0$) and decreases for electron doping ($\\delta n>0$). Near the neutrality point the functional dependence can be approximately by $\\Delta=\\Delta_0-\\alpha\\, \\delta n$ where $\\alpha\\simeq6\\times10^{-12}$ meVcm$^2$. This effect leads to significant changes of the diffusion constant with doping even at room temper"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1407.4142","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":""},"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"}
