Fabrication and Device Issues for III-N Based Materials and Devices: SUPA Distinguished Visitor Seminar
Everyone is welcome to our SUPA Distinguished Visitor Seminar: Fabrication and Device Issues for III-N Based Materials and Devices by Peter J Parbrook, Tyndall National Institute, University College Cork.
III-N materials are extensively used in the manufacture of visible (blue-green) light emitting diodes and for the production of white light.
They are also used in the manufacture of transistors, especially for high frequency applications. However, there are many challenges to their production. In the first presentation we concentrated on materials and growth issues. Here some issues that challenge the device fabrication and performance will be outlined, including current droop, light extraction in LEDs, and device parameters and issues such as 'slump' in transistors. The practical issues in making devices will also be outlined.
