Vertical GaN on tungsten high-voltage pn-diodes – advancing cost-effective power electronics

Efficient power electronic converters need high blocking strength and low on-state resistance. We demonstrate successful laser lift off based transfer of vertical GaN pn-diodes from sapphire to tungsten, enabling true vertical conduction and reducing resistance by half.
