Bulk properties such as specific heat, paramagnetic susceptibility, and other transport phenomena of conductive solids depend on this function.
To determine whether a material is a metal or an insulator, and to calculate the magnitude of the current under applied bias, we need the density of states (DOS), which as you recall is a measure of t...To determine whether a material is a metal or an insulator, and to calculate the magnitude of the current under applied bias, we need the density of states (DOS), which as you recall is a measure of the number of states in a conductor per unit energy. To calculate the density of states we will employ two assumptions: (i) we will model the conductor as a homogeneous box, and (ii) we will assume periodic boundary conditions.
