摘要

We report on the growth and photoluminescence of InGaN/GaN multiple quantum wells (MQWs) grown on GaN nanocrystals embedded in amorphous SiN_x, grown on a p-type Si(100) substrate. p-Type Si(100) was thermally nitridated using NH_3 to form an amorphous SiN_x layer in a metalorganic vapor phase epitaxy system. GaN nanocrystals were then grown on the SiN_x layer, followed by the growth of InGaN/GaN MQWs on the GaN nanocrystals. These nanosize MQWs were capped with amorphous SiN_x in a plasma enhanced chemical vapor deposition system. The findings show that nanosize InGaN/GaN MQWs can be embedded in amorphous SiN_x grown on p-type Si(100) and that these self-assembled nanostructures may be used as new nanosize light-emitting sources as evidenced by photoluminescence from nanosize MQWs.
