Pinch off phenomenon

WebMar 26, 2024 · The pinch-off phenomenon affected the combustion stability as well as the exhaust emissions. Shaddix et al. [30] reported a pinch-off phenomenon wherein the tip of the flame was separated from a nonpremixed flame. They also reported that the soot growth level was four-folds, or more, higher compared with that for a steady flame. WebJun 14, 2024 · Consequently, we deduce that the pinch-off phenomenon is the dominant mechanism of current saturation in the measured devices, and that the device performance is not limited by carrier velocity saturation. 4. Conclusions In summary, a KPFM-based study was conducted to investigate the pinch-off phenomenon in thin-layer MoS 2 FET devices.
