Questiоn 2: Using the infоrmаtiоn below, pleаse drаw approximate band diagrams for the following heterojunctions. Please try to draw the band diagrams to scale on the energy axis as much as you can. Please note the position of the Fermi level(s), EC , EV , and the values of Eg on each side, ΔEC , ΔEV , the values of NC , NV , (EC - EFC) , and (EFV - EV) that are relevant for finding the position of the Fermi level far away from the junction on each side. Please also label the composition and doping type on each side.
