Problems

  1. 8.1 For the p-​i-​n photodiode of Fig. 8–7, (a) explain why this detector does not have gain; (b) explain how making the device more sensitive to low light levels degrades its speed; (c) if this device is to be used to detect light with λ = 0.6 μm, what material would you use and what substrate would you grow it on?

  2. 8.2 We make a quantum well by sandwiching a 60 Å layer of GaAs (Eg = 1.43 eV) between AlAs with a bandgap of 2.18 eV. We can assume two-​thirds of the bandgap difference appear as conduction band discontinuity, and the rest in the valence band. The electron and hole effective masses in GaAs are 0.067 m0 and 0.5 m0, respectively. If we make an LED out of this heterostructure, what is the lowest energy photon that can ...
