Question

For the material described in the previous problem, calculate the wavelength at which a transition from opacity to transparency will occur, and the wave- length at which the reverse transition will occur. Sketch the reflectivity vs. wavelength, with these two wavelengths indicated. 16-6. -3 and 1018 16-5. We form a p-n junction in GaP (E Np 1016 cm3. The dielectric constant is 9, and the effective masses of electrons and holes are 0.35 and 0.5 timeş the free electron mass, respec- tively. Calculate the equilibrium junction voltage. 2.25 eV) using M cm 16-6. For the material described in the previous problem, calculate the wavelength at which a transition from opacity to transparency will occur, and the wave- length at which the reverse transition will occur. Sketch the reflectivity vs. wavelength, with these two wavelengths indicated.
