在分析光吸收光谱和电导数据的基础上，提出了Tl、Pb和Bi的规则三维最小直径(0.6 nm)量子线阵列的电子结构模型。它具有介电类型的能谱、禁带附近类似原子的能带结构、能谱的各向异性以及禁带附近电子态的局域化。
On the basis of the analysis of the optical absorption spectra and conductivity data the model of the electronic structure of the regular three-dimensional arrays of minimum-diameter (0.6 nm) quantum wires of Tl, Pb and Bi has been proposed. It is characterized by a dielectric type of energy spectrum, an atomic-like energy band structure near the gap, anisotropy of this spectrum and localization of the electronic states near the gap.
