摘要: Abstract Transient space-charge-limited current measurement (also called time resolved dark injection) is a well known technique for mobility and contact ohmicity characterization in organic thin films. We demonstrate the feasibility of performing transient measurements using transimpedance amplifier instead typically used bridge circuit. The use significantly simplifies experiment, particularly because it removes requirements symmetry per sample adjustment. Furthermore experimental bandwidth sensitivity are increased. detail experiment design verify compatibility on [6,6]-phenyl-C60-butyric acid methyl ester (60PCBM) blend film.
