论文摘要
Diamond有望重塑超快和高功率电子产品。这样的固态设备之一是二极管雪崩塑形器（DAS），它用作超快关闭开关，在该开关中，闭合是由横流器的形成引起的二极管的速度要比10 $^7 $ cm/s快得多。 DAS最突出的应用之一是在Ultrawide Band（UWB）无线电/雷达中。在这里，我们模拟了基于钻石的DAS，并将结果与基于硅的DAS进行了比较。使用漂移扩散模型以混合模式作为理想设备模拟所有DA。模拟表明，钻石DAS有望在锐化基尔诺夫纳秒输入脉冲时胜过Si das。分解场和流媒体速度（与SI相比，钻石的$ 10倍$ 10倍）可能是使用Diamond DAS启用KV低于50 PS的PS进行切换的主要原因。
Diamond holds promise to reshape ultrafast and high power electronics. One such solid-state device is the diode avalanche shaper (DAS), which functions as an ultrafast closing switch where closing is caused by the formation of the streamer traversing the diode much faster than 10$^7$ cm/s. One of the most prominent applications of DAS is in ultrawide band (UWB) radio/radar. Here we simulate a diamond-based DAS and compare the results to a silicon-based DAS. All DAS were simulated in mixed mode as ideal devices using the drift-diffusion model. The simulations show that diamond DAS promises to outperform Si DAS when sharpening kilovolt nanosecond input pulse. The breakdown field and streamer velocity ($\sim$10 times larger in diamond as compared to those in Si) are likely to be the major reasons enabling kV sub-50 ps switching using diamond DAS.
