Morphology and structure of boron nanowires. (a) TEM image of an individual boron nanowire; (b) SAED pattern and (c) HRTEM image, indicating single crystal with a β-tetragonal structure. (d) EDX pattern of boron nanowires. Both the SAED pattern and the HRTEM image of a single boron nanowire show that it has a perfectly single-crystalline β-tetrahedral structure.
