It allows for an easy solution to Schrodinger's equation through the application of Bloch's theorem since this model assumes periodic boundary conditions – and thus, it represents a key development in the Band Theory of solids.
This model can be solved by the transfer matrix method or by the tail cancellation method, which results in the amplitudes of the plane-wave tails damping out at infinity but not changing over the length of a unit cell. This model generally posits an array of square well potentials with width A separated by potential barriers of height V-sub-0 and width B, though it often takes the form where the barrier becomes a delta function. It allows for an easy solution to Schrodinger's equation through the application of Bloch's theorem since this model assumes periodic boundary conditions – and thus, it represents a key development in the Band Theory of solids. FTP, name this ► simplified model proposed in 1930 which calculates the electronic bandstructure of a one-dimensional crystal, a single-electron model named for two guys.
