Abstract EN
Group III nitride semiconductors with direct band gaps have recently become increasingly important in optoelectronics and microelectronics applications due to their direct band gaps, which cover the whole visible spectrum and a large part of the UV range.
Major developments in wide band gap III–V nitride semiconductors have recently led to the commercial production of high-temperature, high-power electronic devices, light-emitting diodes (LEDs), and laser diodes (LDs).
In this study, GaN nanowires were grown on horizontal reactors by chemical vapor deposition (CVD) employing a vapor-solid mechanism.
Many studies have described how to control the diameters of wires in the liquid phase catalytic process, but one-dimensional nanostructures, which are grown using a noncatalytic process, are relatively unexplored due to the challenge of producing high-quality synthetic materials of controlled size.
However, vapor-solid mechanisms to make synthesized nanowires are simple to implement.
We obtained results from GaN nanostructures that were a preferential c-axis orientation from the substrate.
The morphology and crystallinity of the GaN nanowires were characterized by field-emission scanning electron microscopy and X-ray diffraction.
The chemical compositions of GaN with Mn were analyzed by energy dispersive X-ray spectroscopy.
Optical properties were investigated using photo luminescence and cathode-luminescence measurements.
