High quality GaN epitaxial layers were grown on 6H–SiC substrates by using low-pressure metalorganic chemical vapor deposition method. Samples employing a three-period GaN/Al0.08Ga0.92N (100 A/100 A) as a buffer layer produce a good quality GaN epi

We have investigated proton implantation enhanced intermixing of GaAs/AlGaAs quantum wells for H+ doses ranging from 5×1013 to 1×1016 ions/cm2. Implantation of 20 keV H+ followed by a high temperature rapid thermal anneal leads to enhanced diffusio

Hexagonal-phase single-crystal Gd2 O3 is deposited on GaN in a molecular beam epitaxy system. The dielectric constant is about twice that of its cubic counterpart when deposited on InGaAs or Si. The capacitive effective thickness of 0.5 nm in hexagon

The GaN buffer layer was grown on the sapphire substrate by low‐pressure metalorganic chemical vapor deposition (LP‐MOCVD) at 525 °C. The following 1.3 μm epitaxial GaN growth was carried out at 1025 °C. We varied the ramping rate from 12.5 to

The GaAs-AlGaAs double-heterostructure interferometric lasers were successfully grown by molecular beam epitaxy on [011]-oriented-stepped-channelled GaAs(100) substrates. These lasers have a side-mode suppression ratio of greater than 200:1.
