Magnetic studies of GaN nanoceramics

open access: yes, 2006
The synthesis, morphology and magnetization measurements of GaN nanoceramics obtained under high pressure are reported. In particular the effect of grain size on magnetic properties of GaN nanopowders and nanoceramics was investigated.

Исследования остаточных упругих напряжений в многопериодных сверхрешетках GaN/AlN, выращенных на подложке SiC/Si

open access: yesКонденсированные среды и межфазные границы
Впервые методом хлорид-гидридной эпитаксии на гибридной подложке SiC/Si, синтезированной методом согласованного замещения атомов, сформирована многослойная гетероструктура, состоящая из периодически расположенных слоев GaN и AlN.

Nucleation and Growth of GaN/AlN Quantum Dots

open access: yes, 2003
We study the nucleation of GaN islands grown by plasma-assisted molecular-beam epitaxy on AlN(0001) in a Stranski-Krastanov mode. In particular, we assess the variation of their height and density as a function of GaN coverage.

Observation of ferromagnetism above 900 K in Cr-GaN and Cr-AlN

open access: yes, 2004
We report the observation of ferromagnetism at over 900K in Cr-GaN and Cr-AlN thin films. The saturation magnetization moments in our best films of Cr-GaN and Cr-AlN at low temperatures are 0.42 and 0.6 u_B/Cr atom, respectively, indicating that 14% and ...

Autoencoders and Generative Adversarial Networks for Imbalanced Sequence Classification

open access: yes, 2020
Generative Adversarial Networks (GANs) have been used in many different applications to generate realistic synthetic data. We introduce a novel GAN with Autoencoder (GAN-AE) architecture to generate synthetic samples for variable length, multi-feature ...

Improved Current Densities in MgB2 By Liquid-Assisted Sintering

open access: yes, 2005
Polycrystalline MgB2 samples with GaN additions were prepared by reaction of Mg, B, and GaN powders. The presence of Ga leads to a low melting eutectic phase which allowed liquid phase sintering and produces plate-like grains. For low-level GaN additions

Correlation between crystal structure and magnetism in PLD grown epitaxial films of ε-Fe2O3 on GaN

open access: yesScience and Technology of Advanced Materials, 2021
In the present paper we discuss correlations between crystal structure and magnetic properties of epitaxial ε-Fe2O3 films grown on GaN. The large magnetocrystalline anisotropy and room temperature multiferroic properties of this exotic iron oxide ...

Growth of single-crystal gallium nitride [PDF]

open access: yes, 1970
Use of ultrahigh purity ammonia prevents oxygen contamination of GaN during growth, making it possible to grow the GaN at temperatures as high as 825 degrees C, at which point single crystal wafers are deposited on /0001/-oriented sapphire ...
