电子空穴 meaning in English
electron holes
vacant electron site
Examples
- Titanium dioxide is a semi - conductor with wide band gap , and its photocatalysis operates only when it is irradiated under the ultraviolet radiation of sunlight , and also , the electron hole of tio _ 2 has very high reunited rate
但由于tio _ 2为宽禁带半导体,对太阳光的利用仅局限于紫外部分,并且tio _ 2的光生电子空穴复合几率很高。 - Since polymer light - emitting diodes ( pleds ) were invented , much efforts have been made to improve the brightness and efficiency of its electroluminescence for realizing pled commercial application . we investigated several factors influencing the brightness , efficiency and spectrum characteristics of pleds el , especially focused our attention on the processes of carrier injection , transport , recombination and annihilation factors influencing brightness efficiency of organic electroluminescence ( oel ) in doped single and double - layer pleds
本文以提高聚合物器件的效率和亮度为目标，提出了提高及b几种方案，研究了材料性质，器件结构，它们的稳态及瞬态特性及发光机理，特别关注了以兼具电子空穴传输能力的分子及掺杂聚合物作成的单双层掺杂聚合物发光器件中的载流子注入、迁移、复合及湮灭等。 - The negative photoconductivity effect was found in the dimixing phthalocyanine composites . the experiment results indicated that the negative photoconductivity effects were closely related with the partial charge transfer from the center metals to phthalocyanine rings , and the separation efficiency of photocarriers was a key factor to the photoconductivity
结果表明，共混复合后，其光电导性能表现出负效应，并发现酞菁中心金属与其相连的氮原子之间的部分电荷转移是引起复合体系光电导性能变化的根本原因，同时复合体系中的电子空穴对的分离效率是影响光电性能的一个重要因素。
