It is calculated as a function of electron concentration $ns$ and temperature $T$ and compared with $F_{DP} (T, n_s)$ that due to deformation potential coupling. For the $n_s$ around $1\\times10^{12} cm^{-2}$, $F_{VP} (T, n_s)$ is much smaller than $F_{DP} (T, n_s)$ . With increase of $n_s$, $F_{DP} (T, n_s)$ decreases faster than $F_{VP} (T, n_s)$ does. A cross over is predicted and dominant contribution of $F_{VP} (T, n_s)$ can be observed at"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.08553","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"}
