脉冲驱动器 meaning in English

pulse driver

We also investigated el characteristic of double - layer pleds , ito / pvk - dcjtb / alq / lif / al , by similar method . this method was successfully used for getting directly information of carrier injection , accumulation , tunnel and annihilation between two layers . the mutual injection between organic layers and recombination zone can be adjusted by changing the concentration of dopants in blends
( 3 )在ito / pvk - dcjtb / alq / lif / al结构的掺杂双层有机电致发光器件中，利用脉冲驱动器件，监测两个瞬态电致发光峰值的方法，研究了不同掺杂浓度下的混合薄膜与alq界面处的载流子积累、相互隧穿注入以及载流子湮灭等过程，并利用掺杂浓度调节了界面处的载流子相互隧穿几率，改变了复合发光区域。
