Show Your Work: For each problem, show all the steps involved in your calculations. This includes equations used, substitutions made, and the final answer. 2. Include Units: Make sure to include units for all quantities (e.g., meters, seconds, etc.) in your calculations. 3. Be Neat: Present your work clearly.  Question 1 1 pts For all the following five problems (1,2,3,4, and 5) Assume p-type silicon at room temperature, uniformly doped with NA = 1017 cm-3,τ = 8*10−6 s. Assume Nv = 1.84×1019 cm-3 and Nc = 2.8×1019 cm-3 .The sample is uniformly illuminated with light, resulting in an optical generation rate R = 1020 cm-3 sec-1. 1-Find the equilibrium electron concentrations.
