Given:
To find: The electric current carried by electrons due to drift.
To find: The electric current carried by holes due to drift.
To find: The diffusion current of electrons.
Since the electron density is decreasing from left to right (x-coordinate increases from left to right) ,that means the electron density will be higher on the left side than that on the right side. Therefore the current carried by electron due to diffusion will be from .
To find: The current carried by the holes due to diffusion.
Since the hole density decreases from left to right (because x-coordinate increases from left to right ), the hole density on the left side will be higher than that on the right side.
The hole current due to diffusion will flow from high hole density to lower hole density. i.e.
The current carried by holes due to diffusion will flow from
