Consider a slab of silicon 5 m thick. Determine the percentage of photon energy that will pass through the slab if the photon wavelength is : (a) = 0.8 m and (b) = 0.6 m. Calculate the generation rate of electron-hole pairs given an incident intensity of photons. Consider gallium arsenide at T =300 K. Assume the photon intensity at a particular point is 1 (x) = 0.05 W/cm at a wavelength of = 0.75 m. This intensity is typical of sunlight, for example.
