15-4. As shown in Fig. 15.2, the density of occupied states in the conduction band goes through a maximum slightly above theEx Z(E) F(E) F(E) Z(E) Figure 15.2. Density of available states Z(E), Fermi function F(E), and product Z(E)F(E), the densityZ,(E) = C,(E - E)

15-4. As shown in Fig. 15.2, the density of occupied states in the conduction band goes through a maximum slightly above the bottom of the band. Calculate the energy separation (in eV) between the position of this maximum and the bottom of the band at T 300 K. You may assume that the density of states is of the form shown in equation (15.1)
Ex Z(E) F(E) F(E) Z(E) Figure 15.2. Density of available states Z(E), Fermi function F(E), and product Z(E)F(E), the density of occupied states, near the bottom of the conduction band.

    EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...
