GaN nanocolumns including a GaN/AlN superlattice SL region were grown by rf-plasma assisted molecular beam epitaxy. The photoluminescence PL peak intensity of the GaN/AlN SL nanocolumns was 300∼500 times stronger than that of conventional GaN continuous films with a dislocation density of 3∼5×10 9 cm −2 and thickness of 3.75 μm.

Nowadays, GaN‐based devices are usually grown on sapphire or silicon‐carbide substrates. These are either insulating or very expensive and not available in large diameter. A well‐conducting low‐cost. Volume 831 Symposium E – GaN, AlN, InN, and Their Alloys 2004, E11.6 Direct AFM Observation of Strain Effects on MOCVD-Grown GaN Epilayer Surface Morphology. Given the expected similarities in the crystal physics for the GaN/AIN and the InN/AIN systems and the highly encouraging recent results for MOCVD growth of GaN on AIN surface-modified substrates [ 12], it was of interest to study the effects of a thin AIN buffer layer on the physical properties of reactive r.f. magnetron sputtered InN.

This presentation reviews recent lattice location studies of rare earth RE ions in GaN by electron emission channelling EC and X-ray absorption fine structure XAFS techniques. These studies agree that RE ions at low concentrations whether they are incorporated during growth or introduced later by ion implantation predominantly occupy Ga substitutional sites, as expected from. We have made AlGaN ∕ GaN high electron mobility transistors with a Si 3 N 4 passivation layer that was deposited in situ in our metal-organic chemical-vapor deposition reactor in the same growth sequence as the rest of the layer stack. The Si 3 N 4 is shown to be of high quality and stoichiometric in composition. It reduces the relaxation, cracking, and surface roughness of the AlGaN layer. Attention is paid to the crystal growth techniques, structural, optical, and electrical properties of GaN, AlN, InN, and their alloys. The various theoretical results for each material are summarized. Jun 07, 2001 · We present a comprehensive, up-to-date compilation of band parameters for the technologically important III–V zinc blende and wurtzite compound semiconductors: GaAs, GaSb, GaP, GaN, AlAs, AlSb, AlP, AlN, InAs, InSb, InP, and InN, along with their ternary and quaternary alloys. Based on a review of the existing literature, complete and consistent parameter sets are given for all.
The structural properties and lattice dynamics of Ga1−xMnxN were studied for Mn concentrations from 0.0% to 1.5%. Ga1−xMnxN layers were fabricated by either Mn incorporation during the metal-organic chemical vapor deposition MOCVD growth process or by postgrowth ion implantation into MOCVD-grown GaN epilayers. The crystalline integrity and the absence of major second phase contributions. Thin films of III‐V nitride semiconductors AlN, GaN, InN, mixed‐crystalline films Al x In 1-x N, and multilayered films GaN/InN n were grown by rf magnetron sputtering at low substrate. M.

T he GaN fever grew white hot with the December an- nouncement by Nichia Che- mical of a GaN-based diode laser, which is the shortest wavelength semiconductor laser ever made, and is expected to profoundly impact optical storage applications. EGW-1 will be the first major meeting on European soil dedicated to GaN and its alloys with InN and AIN.
