Abstract: Oriented gallium nitride (GaN) nanowires grown on Pt-coated Si (1 1 1) substrates,
were synthesised using the chemical vapour deposition method under different Ga sources. The
characteristics of the grown GaN nanowires were investigated using scanning electron
microscopy and X-ray diffraction, which found that the as-synthesised GaN nanowires of the
three samples are of different orientation, and all displayed hexagonal wurtzite structures of GaN
crystals. The electron field-emission properties of the three samples of GaN nanowires showed a
low turn-on field of 4.5, 5.5 and 6.2 V/m, respectively, and field enhancement factors of 1337,
2948 and 2599, respectively. © 2012 The Institution of Engineering and Technology.
