| 中文摘要 | we analyze current versus voltage data obtained using single carrier injection in several metal/polymer/metal sandwich structures. the polymer used in each case is a soluble blue-emitting alternating block copolymer. our experimental results demonstrate that the electron transport is space-charge limited by the high density of traps having an exponential energy distribution (temperature dependent characteristic energy) in the copolymer. the electron mobility of 8x10(-10) cm(2)/v s is directly determined using space-charge-limited current analytical expressions. hole transport is also space-charge limited, with a mobility of 2x10(-6) cm(2)/v s. a hole trap with energy 0.17 ev is observed. we compare these results with those obtained for related block copolymers with different spacer and conjugated segment lengths and discuss the influence of spacer length and conjugated segment length on the charge transport properties.
