Guided Growth of Horizontal GaN Nanowires on Quartz and ...

2021-3-12  We have demonstrated the guided growth of horizontal GaN nanowires on different planes of quartz and their transfer to silicon wafers. We showed that horizontal GaN nanowires can have a variable degree of alignment on different planes of quartz. Under our synthetic conditions, the best aligned arrays were obtained on X-cut and Y-cut quartz.

We have studied the growth of gallium nitride on c-plane sapphire substrates. The layers were grown in a horizontal metalorganic chemical vapor deposition reactor at atmospheric pressure using trimethylgallium (TMG) and ammonia (NH3). Variation of the V/III ratio (150–2500) shows a distinct effect on the growth rate. With decreasing V/III ratio, we find an increasing growth rate.
