Question 3 (15 points) A semiconductor is characterized by the idealized energy-band diagram shown in the figure below. Sketch the potential and the electric field profile as a function of x. What is the magnitude of the electron drift current density at ? Is there any electron diffusion current at ? If there is diffusion current, what is the direction of the current? What is the magnitude of the total current at ?
