The Japanese Journal of Applied Physics (JJAP) is an international journal for the advancement and dissemination of knowledge in all fields of applied physics. The journal publishes articles dealing with the applications of physical principles as well as articles concerning the understanding of physics that have particular applications in mind. The journal not only covers all aspects of modern technology such as semiconductor devices including VLSI technology, photonic devices, superconductors, and magnetic recording but also covers other diverse areas such as plasma physics, particle accelerators, nanoscience and technology, and applied bioscience. Articles in interdisciplinary areas with potential technological implications are strongly encouraged.JJAP is published monthly and is for Regular Papers, Rapid Communications, Brief Notes, and Review Papers. Rapid Communications are published bimonthly online. In addition, several Special Issues are published each year. These contain monographs from international conferences and up-to-date findings of research groups.Comments and replies are also published. This section includes the comments on papers previously published in JJAP, and a replies to those.There is also a special section, “Selected Topics in Applied Physics” that highlights specific topics in applied physics. This section features rapidly developing current trends in the selected research area. .
