First Principles Study

First-principles studies on electronic structures, transverse polarizability, and shielding of two coaxial hybrid double-walled nanotubes consisting of carbon nanotube (CNT) and boron nitride nanotube (BNNT), namely CNT@BNNT and BNNT@CNT, are conducted. The interaction between inner and outer tubes is considerably weak. The polarizability of single-walled CNT is larger than that of single-walled BNNT due to the different electronic properties. In BNNT@CNT, the outer CNT with delocalized π-electrons character demonstrates a nearly complete shielding with the order of 90% of the inner BNNT from the transverse external electric field, while the outer BNNT has a relative small shielding of about 40% for the inner CNT in CNT@BNNT system. Moreover, the shielding of the outer tube can be appreciably enhanced by increasing the intertube separation.
