Second-order susceptibility from a tight-binding Hamiltonian Academic Article uri icon


  • Using a new formalism that modifies a tight-binding Hamiltonian to include interaction with a time-dependent electromagnetic field, we have obtained an analytical expression for the second-order susceptibility. This expression has been used to calculate the energy dependence of (Formula presented) for GaAs. The results are in agreement with previous calculations and with available experimental data. 1998 The American Physical Society.
