Scope

Applied Physics Express (APEX) is a Letters journal devoted solely to rapid dissemination of up-to-date and concise reports on new findings in applied physics. The motto of APEX is high scientific quality and prompt publication. APEX is a sister journal of the Japanese Journal of Applied Physics (JJAP) and is published by IOP Publishing on behalf of the Japan Society of Applied Physics (JSAP) APEX publishes articles dealing with the applications of physical principles as well as articles concerning the understanding of physics with particular applications in mind. As a Letters journal, emphasis will be given to developing and emerging fields in applied physics. Examples of fields of current interest include: Semiconductors, dielectrics, and organic materials Photonics, quantum electronics, optics, and spectroscopy Spintronics, superconductivity, and strongly correlated materials Device physics including quantum information processing Physics-based circuits and systems 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.

Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
