abstract = {Gallium nitride materials are at the forefront of
nanoelectronic research due to their importance for UV
optoelectronics. In this contribution, we present a facile
and well-controlled synthesis of GaN nanodisks by rapid
thermal ammonolysis of complex gallium fluoride precursor.
We observed the formation of GaN nanodisks in 150 s at 800
°C. The structural properties of GaN were investigated by
X-ray diffraction, Raman spectroscopy, and
micro-photoluminescence. The morphology of GaN was
investigated by scanning electron microscopy and the
magnetic properties by superconducting quantum interference
device (SQUID) techniques. The morphology of nanodisks was
strongly influenced by the temperature of synthesis. The
structure characterization shows a high concentration of
defects related mainly to the vacancies of N and Ga. The
magnetic measurement by SQUID shows paramagnetic behavior
induced by structure defects. These findings have a strong
implication on the construction of modern optoelectronic
nanodevices.},
