Webb24 nov. 2010 · At a low excitation power density, PL intensity of undoped InGaN well was significantly decreased, while those of interfacial and full Si-doped InGaN well were … Webb14 maj 2024 · ments, we have shown that in the case of n-type doping of GaN and InGaN with Ge it is possible to produce electron concentrations in the range from 4 to 8 × 1020 cm−3 [8]. P-type doping of GaN and InGaN alloys is more difficult because magnesium is the only dopant that can be effectively used to obtain p-type conduction. WebbFinally, MQWs were fabricated on SiO 2 /Si (100) substrate and strong PL opticals, and the I-V curve shows a turn-on voltage of 5.7 V. This study provides an effective method to grow GaN-based LEDs on the amorphous substrate by integrating graphene along with the AlGaN nanorods as buffer layers, which is beneficial for the application of large-area … honeyman morris inc
