Non-presenting attendee seats are fully booked.Publication on Power Electronic Devices and Components (PEDC)
This year GaN Marathon has stipulated an agreement with the new Elsevier Journal Power Electronic Devices and Components (PEDC).
Presenting authors will have the possibility of submitting an extended version of their abstract to a special issue of PEDC. After review and upon acceptance, the extended abstract will be published on PEDC, giving high visibility to the related results.
Power Electronic Devices and Components is a new gold open access journal, therefore contributing to this special issue will be an opportunity for you to play a leading role in defining the scope and development of this new title. We believe that the GaN Marathon special issue will be an outstanding contribution to our community’s understanding of the topic.
Note that open access fees will be waived for GaN Marathon attendees.
