Enhancing photocurrent transient spectroscopy by electromagnetic modeling [PDF]

Review of Scientific Instruments, 2012
The shape and duration of photocurrent transients generated by a photoconductive switch depend on both the intrinsic response of the active material and the geometry of the transmission line structure. The present electromagnetic model decouples both shape forming contributions.
