Abstract

The migration of nitrogen is examined in β−Ga2O3 to determine if diffusion is governed by molecular or monatomic diffusion. Special samples are grown by pulsed laser deposition where the isotopes 14N and 15N are spatially separated. This is verified by secondary-ion-mass spectrometry measurements. Insight into the migration process is obtained from gas effusion. The experimental data provide clear evidence for monatomic nitrogen diffusion in β−Ga2O3.

单原子氮在β-Ga2O3中的扩散

在β−Ga2O3中检测氮的迁移，以确定扩散是由分子还是单原子扩散控制的。采用脉冲激光沉积的方法，将同位素14N和15N在空间上分离。二级离子质谱测量证实了这一点。对运移过程的洞察来自于气体的渗出。实验数据为单原子氮在β−Ga2O3中的扩散提供了明确的证据。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
