The system is stable up to T ~ 3500–3700 K. As the temperature increases, deformations of the BN tube begin earlier than those of the carbon tube. The near-Fermi states of the nanocable are formed by the overlapping p–p* bands of the carbon tube, and the outer BN nanotube (the nanocable sheath) is an insulator with a bandgap of ~4 eV. The electronic properties of the nanocable (the metallic-type conductivity of the C tube and the insulating character of the BN tube) are retained over the entire temperature interval Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Seifert, G.; Ivanovskii, A.
