Compared growth mechanisms of Zn-polar ZnO nanowires on O-polar ZnO and on sapphire.
Controlling the growth of zinc oxide nanowires is necessary to optimize the performance of nanowire-based devices such as photovoltaic solar cells, nano-generators, or light-emitting diodes. With this in mind, we investigate the nucleation and growth mechanisms of ZnO nanowires grown by metalorganic vapor phase epitaxy either on O-polar ZnO or on sapphire substrates. Whatever the substrate, ZnO...
متن کاملGrowth and Characterization of III-V Nanowires and Nanoneedles by
Integration of optoelectronic materials with silicon is an important area of study, which could enable silicon CMOS-integrated optical devices for chip-scale optical communication, with the potential for higher bandwidth and lower costs. However, optical-quality III-V thin-film growth on silicon is difficult due to the crystal lattice-mismatch between the materials, and III-V growth typically r...
متن کاملDoping Behavior of (112̄2)-GaN Grown on Patterned Sapphire Substrates
We present results of the investigation on the doping behavior of planar semipolar (112̄2)oriented GaN grown on (101̄2) patterned sapphire substrates mainly focusing on the magnesium incorporation. We observed that Mg is incorporated with much lower efficiency into the (112̄2) plane as compared to polar c-plane GaN. This problem could be decreased by varying the growth temperature. On the one hand...
متن کاملHigh-efficiency InGaN-based LEDs grown on patterned sapphire substrates.
GaN films grown on PSS are investigated by XRD, CL, SEM and TEM. There are low threading dislocations (TDs) with larger fill factor, which results in better electrostatic discharge (ESD) yield of LEDs. The effect of growth rate on dislocations in GaN films grown on PSS is investigated by TEM. It is found that dislocations density decreases as the growth rates decrease. And the performance of In...
متن کاملControlling The Growth Direction of ZnO Nanowires on c-Plane Sapphire
Well oriented vertical ZnO nanowires (NWs) are grown on c-plane sapphire via a vaporphase transport process using an Au thin film as a catalyst. This new finding is unexpected due to the fact that the lattice mismatch between the zinc oxide and the underlying substrate is 18%. Xray diffraction (XRD) analysis shows that single-crystal, wurtzite NWs grow in the [0001] direction normal to the basa...
