Sic terahertz
WebSilicon carbide (SiC) is widely used in high power electronic devices. However, defects on the SiC significantly reduce the yield and decrease the performance of SiC. Accurate detection of the defects is essential in the process control. We demonstrated a noninvasive three-dimensional (3D) defect detection method for SiC using optical coherence … WebAbstract. The dynamic performance of wide-bandgap 4H-SiC based double drift region IMPATT diode is simulated for the first time at terahertz frequency (0.7 Terahertz) region.The simulation experiment establishes the potential of SiC based IMPATT diode as a high power ( ) terahertz source.The parasitic series resistance in the device is found to …
