FET/TFT Figure Digitization

Extract a transfer or 4PP curve, then calculate FET mobility.

Figure extraction is approximate; CSV/XLSX is more accurate.

Step 2 — Axis Calibration

If a coloured anchor is not on a numbered tick, use Relocate.

How to fill the four values

Enter the number printed at each coloured tick. Example: 10⁻¹⁰ → 1e-10.

X scale

Y scale

Y-axis quantity (as plotted)

Current unit

Per channel width

Example: for µA/µm, choose µA and /µm.

Waiting for automatic geometry detection. The detector retries multiple contrast levels before asking for a clearer crop.
