12 The Influence of the Gate Trench Orientation to the crystal Plane on the Conduction Properties of Vertical GaN MISFETs for Laser Driving Applications
18 Sep 2020 | | Contributor(s):: E. Bahat Treidel, O. Hilt, H. Christopher, A. Klehr, A. Ginolas, A. Liero, J. Würfl
In this work the development of vertical GaN MISFET technology is focused on pulsed laser driving applications with maximum voltages < 100 V (Fig. 1). Drivers for pulsed lasers are required to deliver very high currents up to 250 A in very short pulse lengths of 3 ns to 10 ns .
