In The Space Below Sketch The Energy Band Diagram Of A P N P Bipolar Junction Tr

In the space below, sketch the energy band diagram of a P-N-P bipolar junction transistor (pnpBJT) biased in the Active mode of operation (not cut-off or saturation).Accurately label Emitter (E), Base (B), and Collector (C) regions.For each of the E, B, and C regions, accurately label conduction band (Ec), valence band (Ev),Fermi level (Ef), intrinsic Fermi level (Ei), potential barriers between the two junctions (VEB andVBC).Answer the following questions and provide explanation:1) In the Base, which is higher, donor concentration or acceptor concentration?2) Is the Emitter-Base junction forward biased or reverse biased?3) Is the Base-Collector junction forward biased or reverse biased?4) Considering the useful (desirable) component of the collector current, what type ofcarriers – electrons or holes – are responsible for that current? Where do they come from?
