Question 1: [30 Points] For a certain semiconductor material, EG-1.5 eV, Fermi level is located 1.49 eV above the highest level of the valence band. If E₁ is located 0.002 eV above the bottom of the conduction band, assume room temperature (T-300 K) and KT= 0.026 eV Answer the following: a) [10] What is the probability that a state in the conduction band with energy E=E₁ is occupied? b) [15] Find the density of states at energy level E₁, if the semiconductor material is Si. c) [5] What type of semiconductor material is described in the question p-type n-type intrinsic semiconductor
