Question
a) Explain the term "Fermi Level". Prove that Fermi level in an intrinsic semiconductor lies midway in the forbidden band i.e $E_f = \frac{E_c + E_v}{2}$. Discuss the variation of fermi level with temperature for an n-type semiconductor. (10)
b) Differentiate between quarter & half wave plates. Explain the principle, construction and working of a Nicol prism. (10)
