Work Function

Current status: READY

For a neutral slab with a well-defined vacuum region,

$$\Phi = V_{\mathrm{vac}} - E_F.$$

Quantum Studio identifies the nonperiodic direction, computes a planar potential profile, finds a vacuum plateau, and reports plateau stability.

Charged slabs or missing Fermi-energy provenance are blocked because the simple work-function interpretation would be unreliable.
