“…PAPER incorporation of nitrogen in the carbon nanotips in a nitrogen environment using plasma-assisted hot filament CVD. [26][27][28] This inspires us to try to synthesise GaN NWs using plasmaassisted hot filament CVD in a nitrogen environment. In this work, GaN powder was used as the Ga source and nitrogen and hydrogen were used for the reactive gases, the wurtzite GaN NWs were grown on silicon substrate deposited with a thin gold film by plasma-assisted hot filament CVD in a nitrogen and hydrogen environment.…”
