Understanding Silicon Carbide Schottky Diode Characteristics

Silicon silicon-carbide Schottky rectifiers are gaining increasing traction in high-power fields due to their superior characteristics compared to traditional silicon-based competitors. A key element influencing their effectiveness is the minimization of reverse leakage. Elevated temperatures, a common phenomenon in power electronics, exacerbate this issue, demanding careful evaluation of device architecture. The Schottky contact height, based on the work function of the electrode and the SiC surface condition, is a critical value to control for optimal behavior. Furthermore, effective resistance, stemming from the material material and interfaces, can degrade effectiveness and generate unwanted heat. Therefore, a complete understanding of these effects is essential for reliable power system design and optimized integration.
