摘要
A series of AIN nanostructures were synthesized by an ultrahigh-temperature, catalyst-free, physical vapor transport（PVT） process. Energy dispersive X-ray spectroscopy（EDX）, X-ray diffraction（XRD）, X-Ray photoelectron spectroscopy（XPS）,high resolution transmission electron microscopy（HRTEM） detection show that high quality AIN nanowires were prepared. Nanostructures including nanorings, nanosprings, nanohelices, chainlike nanowires, six-fold symmetric nanostructure and rod-like structure were successfully obtained by controlling the growth duration and temperature. The morphology evolution was attributed to electrostatic polar charge model and the crystalline lattice structure of AIN.
