Both spontaneous and reverse - bias assisted recoveries of device performances were observed , and these degradation and recover } " phenomena were discussed in terms of the movement of ionic impurities and the formation of permanent and induced electric field dipoles in organic layers 文中定性的比较了在中断电场和反向电场前后的发光特性变化,定量的给出了中断电场和反向电场前后发生器件性能衰变的恢复程度。
Experimental results indicated that for the two reverse - bias stresses the degradation of the devices depended on magnitude and energy of the injected carriers . fc stress condition may speed up the degradation of devices and shorten the time of evaluating the devices life 在实验中我们发现对这两种应力,器件的退化与注入的热载流子的数量以及能量有关, fc应力方法可以加速器件的退化,缩短评估器件寿命的时间。
In this thesis two reverse - bias electrical stress methods were used to investigate the reliability of the devices . one is a typical of oc stress method with collector open and reverse - bias emitter - base junction . another one , a new technique , is fc stress method with forward - bias collector - base junction and reverse - bias emitter - base junction 本论文采用两种反偏电应力方法考察器件的可靠性,一种为传统的oc应力(集电极开路,发射结反向偏置)方法,另一种为新的方法fc应力(集电结正向偏置,发射结反向偏置)方法。
The purpose of introducing ferroelectric polymeric pvdf material was to make use of the remanent polarization of ferroelectric materials and to study the effect of the internal field formed in the device during the device worked . the diodes were driven at constant voltage and were also kept under short - circuit or reverse - bias conditions 本文将具有特殊极化性能的铁电高分子材料pvdf引入器件,目的在于利用其电场下其残余极化特性,研究此种器件工作时形成的内电场情况及其对器件稳定性的影响。
