Solid State Physics

Consider a one-dimensional (1-D) atomic lattice with an interatomic spacing of 5 angstroms (Å). Each atomic site can be represented by a rectangular-shaped potential well of 1 eV depth and width of 1 angstrom (Å). Estimate the following parameters: The width of the 2nd lowest energy band (in eV).

Atomic interactions can be modeled using a variety of potential energy approximations. One very common potential form is the Lennard-Jones 6:12 potential: U(r)=4ε[(σ/r)12 − (σ/r)6]. Where ε and σ are constants specific to a given material (note: these terms are NOT equivalent to stress and strain, but this is the standard notation for the L-J parameters). Here, r is the interatomic spacing given in units of Angstroms, and U(r) is given in units of eV/atom. A molecular dynamics simulation was...
