Understanding Silicon Carbide Schottky Diode Operation
Silicon silicon-carbide Schottky devices are gaining significant traction in high-power applications due to their superior operation compared to traditional silicon-based counterparts. A key aspect influencing their effectiveness is the lowering of reverse current. Elevated temperatures, a common occurrence in power electronics, exacerbate this issue, demanding careful assessment of device architecture. The Schottky junction height, based on the work function of the electrode and the SiC surface potential, is a critical characteristic to control for optimal response. Furthermore, parasitic resistance, originating from the substrate material and connections, can degrade effectiveness and generate excessive heat. Therefore, a complete understanding of these effects is essential for reliable power network design and successful integration.
