The Fermi energy for copper is Eg = 7.00 eV. For copper at T= 1000 K, (a) find the energy of the energy level whose probability of being occupied by an electronis 0.923. For this energy, evaluate (b) the density of states N(E) and (c) the density of occupied states N (E). (a) Number n Units v (b) Number n Units v (c) Number n Units v The Fermi energy of a certain metal is 11.5 eV, its density and molar mass are 3.29 g/cm and 28.1 g/mol, respectively. From these data, determine the number of conduction electrons per atom. Number u Units v What is the number of occupied states in the energy range AE = 0.0307 eV that is centered at a height of E = 6.29 eV in the valence band if the sample volume is V = 5.30 x 10-8m3, the Fermi level is EF = 5.02 ev, and the temperature is T = 1560 K? Number Units V
