Optical and Vibrational Properties of Boron Nitride Nanotubes

L. Wirtz, A. Rubio

As for carbon nanotubes, optical and vibrational spectroscopy - in particular Raman and luminescence spectroscopy - play an important role for the characterization of BN nanotubes. In this chapter we review, from a theoretical view point, the different spectroscopic techniques that are currently used for BN-nanotubes and make a close link with available experimental data. We summarize experimental and theoretical data on Raman spectroscopy, optical absorption spectroscopy, luminescence spectroscopy, and electron-energy loss spectroscopy. The combination of all those methods allows for a fairly complete characterization of the electronic structure and the vibrational properties of BN tubes. Possible applications in optoelectronic devices are briefly discussed.
