The journal publishes articles dealing with the applications of physical principles as well as articles concerning the understanding of physics with particular applications in mind. However as a letter journal, emphasis will be given to developing and emerging fields in applied physics. A work of high originality but concerning a field not in a competitive area may be suggested to be submitted to the JJAP Communication section. Examples of fields of current interest includes:

   Semiconductors, dielectrics, and organic materials
   Photonics, quantum electronics, optics, and spectroscopy
   Spintronics, superconductivity, and strongly correlated materials
   Device physics including quantum information processing
   Nanoscale science and technology
   Crystal growth, surfaces, interfaces, thin films, and bulk materials
   Plasmas, applied atomic and molecular physics, and applied nuclear physics
   Device processing, fabrication and measurement technologies, and instrumentation
   Cross-disciplinary areas such as bioelectronics/photonics, biosensing, environmental/energy technologies, and MEMS

All submissions to the journal must be submitted online at
