Which of the following statements is NOT true for diode saturation current (I0)?
1
I0 can vary by orders of magnitude depending on the dopant concentrations.
2
I0 can be viewed as the drift current due to majority carriers generated within a diffusion length of the depletion region.
3
I0 is the rate at which carriers are thermally generated within one diffusion length of the depletion region.
4
I0 can vary by orders of magnitude depending on the semiconductor material.
