英文摘要	Arrays of single-crystalline aluminum nitride nanotubes (AINNTs) were successfully synthesized at 780 degrees C by a facile CVD method without templates or catalysts. Faceted hexagonal AINNTs with diameters from tens to hundreds of nanometers were observed. 264 nm deep-ultraviolet emission associated with Al vacancies was detected by photoluminescence. Raman characterization indicates that the lattice of the AINNTs is notably defective, and disorder-activated silent B-1 (low) and B-1 (high) were detected at 583.0 and 730.0 cm(-1) respectively, which were allowed by the breakdown of the translational crystal symmetry. The redshift of E-2 (high) Raman modes indicates that biaxial tensile stress exists in the samples. (C) 2014 The Japan Society of Applied Physics
