 abstract = {Boron Nitride Nanotubes (BNNTs) have alternating boron and nitrogen
atoms in graphite like network and are strongly polar in nature due to a
large charge on boron and nitrogen atoms. Hence electrostatic
interactions are expected to play an important role in determining the
elastic properties of BNNTs. In the absence of specific partial atomic
charge information for boron and nitrogen, we have studied the elastic
properties BNNTs varying the partial atomic charges on boron and
nitrogen. We have computed Young modulus (Y) and Shear modulus (G) of
BNNT as a function of the tube radius and number of walls using
molecular mechanics calculation. Our calculation shows that Young
modulus of BNNTs increases with increase in magnitude of the partial
atomic charge on B and N and can be larger than the Young modulus of
CNTs of same radius. This is in contrast to the earlier finding that
CNTs has the largest tensile strength (PRL, 80, 4502, 1998). Shear
modulus, on the other hand depends weakly on the magnitude of partial
atomic charge and is less than the shear modulus of the CNT. The values
obtained for Young modulus and Shear modulus are in excellent agreement
with the available experimental results.},
