摘要

Chemical vapor deposition (CVD) method is employed in the present paper to grow patterned Aluminium nitride (A1N) nanowire array. The AlN nanoarray is grown on Si substrate through patterned polystyrene spheres (PS) colloid template. The microstructure of A1N nanoarray is investigated by SEM, XRD and Photoluminescence (PL) spectrum. The results show that the full width at half-maximum (FWHM) of the XRD diffraction peaks of AlN nanostructure are very narrow, which means the good crystalline structure of the AlN nanowire. From the SEM photos, the cyclical morphology of the A1N nanostructure can be observed. The cycle is equal to the diameter of the PS template. The PL spectrum of the patterned AlN indicates that a strong and narrow band of 3.8 eV is emitted in the patterned AlN sample, which is due to the nitrogen vacancies in AlN.
