The Schrodinger equation for V(x) = - V0 csc2(πx/a) is solved. E(k) and the effective mass are examined along with the wave functions for various values of the parameter (V0a2). It is found that the wave functions have intermediate forms even when m* ≈ m, m* ≈ ∞, and that the weak- and tight-binding approximations are not valid in these regions.
