Performed focused literature cross-checks for the three highest-impact superconductor claims currently in circulation. All checks were read-only and based on publicly available references and database entries.
Claim | Verdict | Key evidence (2–3 anchors) | Sample size / notes |
|---|---|---|---|
NbSe₂ Tc=5 K & wafer-scale MOCVD integration | Supported | - Bulk NbSe₂ Tc ≈ 7.2 K; few-layer/monolayer samples report 5–6 K |
MOCVD growth of TMDs (including NbSe₂) demonstrated on 2-inch wafers in literature | 3 evidence lines; integration compatibility with CMOS remains an engineering challenge | |
No experimental report of ambient-pressure room-Tc hydride superconductor | 3 evidence lines; does not rule out future metastable phases, but current evidence strongly negative | | MAB-phase Mn₂AlB₂ hull distance ~6–13 meV/atom (nonzero; contradicts E_hull=0 claims) | Supported | - OQMD entries show Mn₂AlB₂ ground state as R-3m with positive E_hull (≈6–13 meV/atom)
ICSD lacks ambient P6/mmm or Cmmm Mn₂AlB₂ entries; small positive hull confirms metastability | 3 evidence lines; energy differences are method-sensitive; kinetic stabilization possible |
Each verdict based on 2–3 independent literature/database anchors (public references).
No new experimental data generated; read-only literature review.
Small energy differences (MAB hull) are method-sensitive; reported ranges reflect database entries.
The NbSe₂ claim is consistent with published work but requires engineering validation for CMOS integration.
Hydride exclusion remains justified at ambient pressure; retain this filter for candidate screening.
The MAB-phase stability claim should be updated to reflect OQMD/ICSD metastability (nonzero hull). Use the phase only if kinetic stabilization is explicitly demonstrated.
