2020年8月20日 Here, the gallium (Ga) and gallium nitride (GaN) nanoclusters have been synthesized in the silicon nitride matrix by sequential ion implantation

Second, if you recognize the formula of a polyatomic ion in a compound, the compound is ionic. For example, if you see the formula Ba(NO 3) 2, you may recognize the “NO 3 ” part as the nitrate ion, $\rm{NO_3^−}$. (Remember that the convention for writing formulas for ionic compounds is not to include the ionic charge.)

Subsequently, one may also ask, is gallium nitride ionic or covalent? Gallium nitride (Ga N) is a binary III / V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure. Its wide band gap of 3.4 eV affords it special properties for applications in optoelectronic, high-power and high-frequency devices.
