Unformatted text preview: Problem 7: Problem 2.36 on p. 71 of Jaeger and Blalock. Use a value of n i = 10 10 cm − 3 for Si at T = 300 K for simplicity, and determine the mobility values first from the graph of Fig. 2.8 on p. 56, and then also by using the “mobility approximations” formulas to the right of the figure. Problem 8: Problem 2.44(a,b,c) on p. 72 of Jaeger and Blalock. Problem 9: Problem 2.50 on p. 72 of Jaeger and Blalock. Problem 10: Problem 2.54 on p. 72 of Jaeger and Blalock. Compute the maximum wavelength λ max in units of microns ( µ m). Does the computed maximum wavelength λ max fall within the infrared, visible, or ultraviolet region of the spectrum? Based on the physics of this situation of optical generation of electron-hole pairs, explain why silicon is opaque in the visible spectrum, but transparent for wavelengths greater than λ max ....
