Overview

Simulation study demonstrates increased threshold voltage and saturation current in gallium nitride transistors, highlighting potential for next-generation high-power devices.

Key Points

  • An embedded p-gan cap combined with a recessed gate and graded algan barrier layer increases device threshold voltage while maintaining circuit operation safety.
  • Threshold voltage reached 8.6 V under optimized gate layer doping, and an added n-well boosted device saturation current to 718 mA/mm to improve overall output.
  • Simulation calculations optimized the hybrid gate structure barrier layer, highlighting that combining a recessed gate with an n-well may enable high-power devices.
