3 A pn step junction is fabricated in silicon with a donor concentration of 1 x 1015 cm on one side on the junction and an acceptor concentration of 5 x 1014 cm 3 on the other. Find Xp, Xn, and the depletion width W at 300 K. (The permittivity of silicon is 11.68€ 0, where is the permittivity of vacuum, &0 = 8.854 x 10-12 F/m.) Select 3 correct answer(s) |Xp = 0.997 μm Xp = 0.550 μm Xp = 0.220 μm Xp = 0.440 μm Xn = 0.498 μm Xn = 0.220 μm Xn = 0.550 μm Χn = 0.770 μm W = 1.50 μm W = 0.770 μm W = 1.20 μm W = 1.11 μm 3 A pn step junction is fabricated in silicon with a donor concentration of 1 x 1015 cm on one side on the junction and an acceptor concentration of 5 x 1014 cm 3 on the other.

Expert Answer:
Answer rating: 100% (QA)
To find xp and xn we need to use the intrinsic carrier concentrations and the donor and acceptor concentrations The intrinsic carrier concentration in silicon is about 108 x 1010 cm3 at room temperatu... View the full answer
