Wm. Steffens et E. Oesterschulze, Scanning force microscope cantilever for voltage sampling with ultrafast time resolution, ELECTR LETT, 35(13), 1999, pp. 1106-1108
A scanning force microscopy (SFM) cantilever for the investigation of ultra
fast signals is presented. High temporal resolution is achieved by integrat
ing a photoconductive switch within a coplanar waveguide structure onto a l
ow temperature GaAs/GaAs cantilever. Experimental results and numerical cal
culations of the detection of picosecond guided electrical signals based on
the optoelectronic technique of photoconductive sampling are presented.
