In a small piece of semiconductor material, the concentration of electrons keeps decreasing from left to right. Then (1) What is diffusion transport (movement) direction of electrons? (2) What is the direction of diffusion current induced by electrons? (The direction of an electric current is by convention the movement direction of a positive charge.)
