Scanning tunneling spectroscopy data of Np2O5 (neptunium pentoxide) measured at room temperature. The dataset includes measurements using both the lock-in technique and direct I(V) collection, indicating a measured band gap of about 1.5 eV. It was authored by Benjamin Heiner and published via Harvard Dataverse in April 2026.
Use Cases
- Validate electronic band structure models based on the reported 1.5 eV band gap.
- Compare measurement fidelity between lock-in and direct I(V) collection techniques mentioned in the description.
- Analyze scanning tunneling spectroscopy signals from neptunium oxide compounds at room temperature.
Strengths
- Includes data from two distinct measurement techniques: lock-in and direct I(V) collection.
- Reports a specific, measured band gap value of about 1.5 eV.
- Associated with a specific research identifier (LA-UR-26-23190).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
