Understanding Silicon Carbide Schottky Diode Performance
Silicon silicon-carbide Schottky devices are gaining growing traction in high-power applications due to their superior characteristics compared to traditional silicon-based competitors. A key aspect influencing their effectiveness is the minimization of reverse leakage. Elevated temperatures, a common occurrence in power electronics, exacerbate this issue, demanding careful evaluation of device layout. The Schottky contact height, based on the work function of the metal and the SiC surface potential, is a critical value to control for optimal behavior. Furthermore, series resistance, stemming from the substrate material and contacts, can degrade yield and generate unwanted heat. Therefore, a detailed understanding of these influences is essential for dependable power system design and optimized integration.
