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 Question 2: [45 Points] Gallium Phosphide (GaP) has a lattice constant a=5.7 Aº, Answer the following: a) [10] Calculate the atomic density of GaP. b) [10] How many valence electrons per m³ are there in GaP? c) [10] Calculate the mass density for Gap if the mass for Ga atom is 150x10-27Kg and the mass for P atom is 60x10-27Kg.
