Dielectric materials are foundational to our modern-day communications, defense, and commerce needs. Although dielectric breakdown is a primary cause of failure of these systems, we do not fully understand this process. We analyzed the dielectric breakdown channel propagation dynamics of two distinct types of electrical trees. One type of these electrical trees has not been formally classified. We observed the propagation speed of this electrical tree type to exceed 10 million meters per second. These results identify substantial gaps in the understanding of dielectric breakdown, and filling these gaps is paramount to the design and engineering of dielectric materials that are less susceptible to electrostatic discharge failure.

电子辐照聚甲基丙烯酸甲酯中高速电树生长动力学


介电材料是我们现代通信、国防和商业需求的基础。尽管电介质击穿是这些系统故障的主要原因，但我们并不完全了解这个过程。我们分析了两种不同类型电树的介电击穿通道传播动力学。其中一种类型的电气树尚未被正式分类。我们观察到这种电树类型的传播速度超过每秒 1000 万米。这些结果表明，在理解介电击穿方面存在重大差距，而填补这些差距对于不易受静电放电故障影响的介电材料的设计和工程至关重要。
