利用电位放电技术研究了三苯胺和双酚A聚碳酸酯二元固溶体中的空穴输运。电荷从非晶硒的光电发射电极注入。在空间电荷受限的条件下，空穴传输可以通过线性依赖于电场的漂移迁移率来描述。对于105 V/cm的电场，迁移率值在10−7和10−5 cm 2/V s之间，取决于温度和浓度。随浓度的变化表明，空穴传输是通过三苯胺分子之间的声子辅助跳跃发生的，电荷局域化半径约为1.8 A。
By means of potential discharge techniques, hole transport has been investigated in binary solid solutions of triphenylamine and bisphenol‐A‐polycarbonate. Charge was injected from a photoemitting electrode of amorphous selenium. Under space‐charge‐limited conditions, hole transport can be described by a drift mobility that is linearly dependent upon the electric field. For fields of 105 V/cm, values of the mobility were between 10−7 and 10−5 cm2/V s, depending upon the temperature and concentration. The variation with concentration suggests that hole transport occurs by phonon‐assisted hopping between triphenylamine molecules with a charge localization radius of approximately 1.8 A.
