The test program (including test method, test sequence, sweeping direction, sweeping rate, sweeping range, and data extraction method) can also have a significant impact on the BTI of
4H-SiC MOS devices.
For one thing, fast and slow traps can both be detected at a low temperature (225 K), but at room and higher temperatures, fast traps cannot be detected [3], leading to a large reduction in the Vfb shift between 225 K and 300 K.

Results and Discussion
Heat transfer coefficient
The samples with the porosity ranging from 0.48 to 0.78, pore size from 250-1500 µm and Cu particle size from 75 to 841 µm were tested in this study at a flow rate of 2.0 L/min.
Although heat transfer coefficient becomes lower when the porosity is higher than 0.7 (Fig. 3), the significant decrease in pressure drop can compensate the reduction in heat transfer coefficient.
