Abstract(in English) | Excess carrier lifetime is an important parameter and reflects crystal quality of semiconductor materials. It affects most of semiconductor devices, especially bipolar devices and high frequency devices. Although SiC is a promising material for high power devices, it has short carrier lifetimes. In this study, we have measured carrier lifetimes in bulk SiC wafers, and have compared them with structural defect and carrier concentration distribution. It was found that relatively long lifetime regions correspond to regions with high density of structural defects in a n-type wafers. Conversely in p-type wafer, relatively short lifetime regions correspond to regions with high density of structural defects. |
