Recombination Factor Calculator

Recombination Factor Calculator

Calculate the recombination factor using the equation:
\[ \eta_{rec} = 1 – \exp\left(-\frac{W_B}{L_B}\right) \] where \(W_B\) is the base width and \(L_B\) is the diffusion length.

* Ensure both parameters are entered in the same units (e.g., µm).

Step 1: Enter Parameters

Example: 1 µm

Example: 3 µm

Formula: \( \eta_{rec} = 1 – \exp\left(-\frac{W_B}{L_B}\right) \)


Practical Example:
For a base width \( W_B = 1 \) µm and a diffusion length \( L_B = 3 \) µm, the recombination factor is calculated as:
\[ \eta_{rec} = 1 – \exp\left(-\frac{1}{3}\right) \approx 0.283 \quad (28.3\%) \]
