Scanning Tunneling Microscopy (STM) — Public Tier

(3 scenes)

Full-access development tier with all data visible.

What you get

Measurements (y), ideal forward operator (H), spec ranges, ground truth (x_true), and true mismatch spec.

How to use

Load HDF5 → compare reconstruction vs x_true → check consistency → iterate.

What to submit

Reconstructed signals (x_hat) and corrected spec as HDF5.

Parameter Specifications

True spec visible — use these exact values for Scenario III oracle reconstruction.

Parameter Spec Range True Value Unit
tip_electronic_structure -0.15 – 0.15 0.0 -
piezo_creep -1.0 – 2.0 0.5 -
tunneling_barrier_height 4.2 – 5.1 4.65 eV
vibration_amplitude -1.0 – 2.0 0.5 pm
