The Section “Microelectronics” of Electronics (ISSN: 2079-9292) is dedicated to publishing original research articles and cutting-edge reviews for the applications of microelectronics in emerging, frontier and challenging technologies. The operation of electronics in extreme environments, such as a vacuum, space, harsh radiation, extreme cold and other niche applications, is pushing microelectronic design beyond the frontier of standard electronics.

As they are of open access format, you have free and unlimited access to the full text of all the articles published in our journal. We welcome you to read our most highly cited papers published in 2021 below:
