DopingMVP
Implant dose (educational)
Estimate the total number of implanted ions from an areal dose and an exposed area.
Inputs
Result
Enter values and calculate to see the result.
Interpretation
Enter an areal dose (ions/cm²) and the exposed area.
Formula
total ions = dose × area
Dose is ions per unit area.
Variables
| Symbol | Variable | Unit |
|---|---|---|
| total ions | Total implanted ions | count |
| dose | Areal dose | ions/m² (entered as ions/cm²) |
| area | Exposed area | m² |
Assumptions & validity
This tool assumes:
- Uniform dose over the exposed area.
- Educational — no energy, depth, or profile modelled.
Worked example
dose = 1×10¹⁴ ions/cm², area = 1 mm² (= 0.01 cm²).
total = 1×10¹⁴ × 0.01 = 1×10¹² ions
