ABSTRACT
Four types of boron nanotubes (BNTs) in the form of double-ring basic units are theoretically predicted. The structure, stability, and electronic properties of these stable BNTs are investigated by the first-principles calculations. The BNT formed by the basic unit with one hole every six atoms on each ring is found to be more stable than those with other three types of basic units. By increasing diameter for boron ring, the stability is enhanced. The density of state demonstrates that BNTs formed by these basic units are metallic.

    The interaction between H2 molecules and boron nitride (BN) single-walled nanotubes with BN divacancies is investigated with density-functional theory. Our calculations reveal that H2 molecules adsorb physically outside defective BN nanotubes, and cannot enter into BN nanotubes through bare BN...

    Boron could be the next element after carbon to form two-dimensional monolayer structures. Using the ab initio global searches, we found all low-lying monolayer boron sheets with 1-4 hexagonal holes in each unit cell. The two most stable boron sheets are composed of two kinds of elementary units...
