The minority carrier lifetime, also known as the average lifetime of non-equilibrium minority carriers, reflects the decay rate of minority carriers in semiconductor materials. It can directly reflect the quality of semiconductor materials and the performance of high-voltage high-power devices. Take the SiC bipolar power [...]

Silicon-based devices are approaching physical limits, and compound semiconductors have broad prospects. Meanwhile, in some high-power, high-voltage, high-frequency, and high-temperature applications (such as new energy and 5G communications), the performance of silicon-based devices has gradually failed to meet the requirements. Due to the excellent [...]
