Fill in the blank: in the band diagram of a p-type semiconductor the ???? band of the dopant is above the ???? band of the semiconductor. Enter your answer with a comma between them (i.e. valence,valence). Do not include a space between the answers. Question 25 What type of semiconductor is formed when silicon is doped with arsenic? Correct 4.00 points out of 4.00 Select one: O a. n-type P Flag question O b. p-type Check Your answer is correct....

4. Label each band diagram below with an appropriate label.(4) Draw the band diagram for a p-type and n-type semiconductor(4). Briefly describe an experiment that you could perform to distinguish between a conductor and a semiconductor (they both look shiny and hard at room temperature).(2) (10 points) (d (rt o :ODH Energy
Draw the energy band diagram at equilibrium for the p+ /n/p semiconductor heterostructure (p+ indicates a p-type semiconductor which is heavily doped, i.e., more heavily doped than p). You should indicate Ec (conduction band), Ev (valence band), Ei (intrinsic Fermi level), and Ef (Fermi level) throughout the device structure. show your work (i.e., you should start from the diagram of individual material pieces). State any reason for your drawing.
Draw the band diagram (the relative positions of conduction band edge EC, valence band edge Ev, Fermi level EF) for the four following cases. Clearly note EC −EF, EF −EV, Ei −EF, EG = EC −EV. Ei is the intrinsic Fermi level. Take NC=NV =1025 m−3, EG=1.1 eV, ni=1.5×1016 m−3, kT=0.026 eV. (Q1.1) p-type, NA=5×1023 m−3. (Q1.2) p-type, NA=5×1021 m−3. (Q1.3) n-type, ND=5×1023 m−3.
