Understanding Silicon Carbide Schottky Diode Operation

Silicon silicon-carbide Schottky rectifiers are gaining significant traction in high-power fields due to their superior characteristics compared to traditional silicon-based alternatives. A key element influencing their effectiveness is the lowering of reverse current. Elevated temperatures, a common phenomenon in power electronics, exacerbate this problem, demanding careful consideration of device design. The Schottky junction height, dependent on the work function of the contact and the SiC surface potential, is a critical parameter to control for optimal response. Furthermore, effective resistance, originating from the bulk material and connections, can degrade efficiency and generate unwanted heat. Therefore, a complete understanding of these impacts is vital for robust power circuit design and successful integration.
