Abstract

Boron nitride nanotubes (BNNTs) possess different electronic and chemical properties in compared with their carbon nanotubes (CNTs) analogues. BNNTs are expected to play an important role in manufacturing of nanodevices because its wide band gap [1]. Replacing the C-C pairs in the CNTs with iso-electronic B-N pairs gives BNNTs alternative functional properties such as pyroelectrict and piezoelectric behavior as well as photogalvanic properties which CNTs do not have [2]. These promising properties of BNNTs generate a large of important potential applications including energy storage, nanotube electronic devices and new composite materials [3]. The range of applications of these boron nitride nanotubes would be extended if their band gap can be tuned to desired values in controlled way. In this research, we apply a theoretical methodology to study the structural and electrical properties, including electrical conductivity of BNNTs using an electric field applied to the tube axis.
