Cubic gallium nitride (GaN) is a promising material for high-frequency and optoelectronic devices due to its superior electronic properties and reduced polarization effects compared to its hexagonal counterpart.
However, growing high-quality cubic GaN is challenging due to the lack of a native substrate and the high density of defects arising from lattice mismatch and thermal expansion differences with available
substrates.
This study focuses on the growth of cubic GaN on 3C-SiC/Si(001). Since 3C-SiC is only available on silicon substrates, achieving high-quality 3C-SiC on Si(001) is itself a significant challenge. Improving the growth process and optimizing interface engineering can enhance the structural and electronic properties of cubic GaN films.
