✦ Synopsis

We study the energy spectrum of the strong-coupled superlattice. The barriers affect the energy spectral statistics in a Ž .

Ž . small scale. The nearest-neighbor energy-level distribution P s and the spectral rigidity D L demonstrated the GOE 3 Ž . Gaussian Orthogonal Ensemble distribution. In the whole scale, with the electric field increasing, the spectral rigidity Ž . D L changes from the Poisson-type like distribution to the Wigner-type like distribution due to the change of the 3 Ž . energy-level long-correlation, while the P s indicates that the system demonstrates to be integrable. The near-degeneracy of levels makes the level statistics complex.
