A) Suppose you wanted to make a photoconductor that interacts in the visible, green light range (500-570 nm). Which of the following semiconductors would be your best choice, and why? Si, AIP, InAs, CdS. Also, discuss why the other three candidates will not be suitable in terms of band gap (value and direct/indirect). B) If this material is illuminated with light and the generated charge carriers have lifetimes tn = tp = 10us and the steady state excess electron concentration is on = 1x10^10cm^-3 1) What is the steady state excess hole concentration, op? ii) What is the optical generation rate, gop? C) If the device has the properties discussed above, what is its photoconductivity change, Ac?
