Description
Summary:Cathode shorts are an essential part in light-triggered thyristors (LTTs) that are utilized to achieve adequate d v /d t capability and switching characteristics. In this paper, we designed cathode shorts structures specifically for small-size LTTs; the patterns and structural parameters were shown. Devices were fabricated and measured, and the influences of the cathode shorts on device performance were examined. The results showed that, based on the optimized design, the cathode shorts allowed excellent d v /d t capability and switching performance while achieving good optoelectronic properties.
