摘要：

We show that both the absolute value and the sharp features in the spectral form of the frequency-dependent third-order susceptibility of semiconductor superlattices (e.g., [8 monolayers (InAs)0.7(GaSb)0.3]/(4 monolayers AlSb)) strongly depend on the shape of the minibands. The significant minibands span a range of energies up to almost-equal-to E(gap) from the fundamental band edges.
