Based on a 28-nm bulk p- FinFET device, we have investigated the fin width and height dependence of bipolar amplification for heavy-ion-irradiated FinFETs by 3D TCAD numerical simulation. Simulation results show that due to a well bipolar conduction mechanism rather than a channel （fin） conduction path, the transistors with narrower fins exhibit a diminished bipolar amplification effect, while the fin height presents a trivial effect on the bipolar amplification and charge collection. The results also indicate that the single event transient （SET） pulse width can be mitigated about 35% at least by optimizing the ratio of fin width and height, which can provide guidance for radiation-hardened applications in bulk FinFET technology.展开更多
为研究小水线面双体船(small water-plane area twin hull,SWATH)的耐波性,在拖曳水池里开展了SWATH顶浪规则波中纵向运动模型试验,研究了航速和稳定鳍纵向位置变化对船体纵向运动性能的影响,以及波高变化对船体运动响应的非线性影响。...为研究小水线面双体船(small water-plane area twin hull,SWATH)的耐波性,在拖曳水池里开展了SWATH顶浪规则波中纵向运动模型试验,研究了航速和稳定鳍纵向位置变化对船体纵向运动性能的影响,以及波高变化对船体运动响应的非线性影响。试验结果表明:不同航速下,船体的垂荡传递函数和纵摇传递函数均随着波长变化呈现出双极值;不同航速时的垂荡传递函数的极值大小变化较小。稳定鳍纵向位置移动3.5%设计水线长时,对模型的运动响应影响不明显。随着波高增加,模型运动响应的非线性特征突出表现在共振区附近,在低速时更为显著。展开更多
