ABSTRACT
The electronic structures, optical absorption spectra, and the modulation of uniaxial strain along tube axis to electronic structures and optical absorption spectra of BeO nanotubes have been studied using the density functional theory. The results show that the absorption spectrum of BeO nanotubes is anisotropic with respect to light polarization and is closely related to the chirality and diameter of tube. The uniaxial strain can effectively modulate the electronic structures and absorption spectra of BeO nanotubes, indicating the armchair BeO nanotubes can be used as the anisotropic device and sensor of photoelectron.
