Special Issue Information
Dear Colleagues,
Over the last couple of decades, wide bandgap semiconductors have moved from material research and into industrial applications within lighting/optoelectronics and high-power electronics. As an example, wide bandgap semiconductors SiC and GaN devices are starting to make an impact on the power device market, especially due to improved semiconductor properties. Key performance parameters include high breakdown field strengths and improved thermal conductivity. While such properties are promising, a number of challenges exist related to device performance stability under application conditions due to oxide quality or interface defects, among others, as well as device variation. This, at least seen from an application implementation point of view, may be seen as a risk compared to the more well-known properties of silicon that have dominated the power market so far. The topic of this issue is focused on the latest development in wide bandgap devices within power, as well as in optoelectronic applications, with special attention paid to how the new semiconductor material and device perform under high load conditions. By combining lessons learned in semiconductor material synthesis with those from device implementation, this Special Issue will help bring knowledge from material development into industrial applications.
Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
