(Color online) Eigenspectrum for , , . The continuum represents single phonon continua and the breather band or phonon bound state due to “impurities” in the upper branch of the spectrum.

(Color online) (a) The variation of the energy gap is shown plotted against the impurity content of . The curve becomes asymptotic around the critical point of the impurity. It is thought that for LiNbO3 type ferroelectrics, there is such a transition point at which working with a practical device will be easier. (b) The bound state energy EBS vs α, showing the transition point according to analytical calculations.
