It is found that in the backward voltage segment of the I-V curve the leakage current is larger because of deep-level-assistant tunneling;

结果表明，相对理想情形，特性曲线的反向偏压区漏电因深能级隧穿偏大；正向小偏压下因沿着位错汇聚金属产生漏电流；

When a backward biasing voltage is applied, the thickness of a depletion layer formed is made large, so that generation of hot carriers is minimized.

当施加反向偏置电压时，形成的耗尽层厚度变大，从而使热载流子的产生减到最小。

Networks are riddled with circuit breakers that prevent electricity from flowing backward to the substation when voltage drops--the moment when utilities need solar cells and basement battery packs to support the grid.
