T. Pfeifer et al., FABRICATION AND CHARACTERIZATION OF FREELY POSITIONABLE SILICON-ON-SAPPHIRE PHOTOCONDUCTIVE PROBES, Journal of the Optical Society of America. B, Optical physics, 11(12), 1994, pp. 2547-2552
A study of external photoconductive sampling is reported. We describe
in detail the fabrication of photoconductive probes on silicon-on-sapp
hire Measurements of electric pulse propagation on terahertz-dipole an
tennas serve to characterize the linearity, the sensitivity, the time
resolution, and the dielectric invasiveness of the probes.
