摘要：
We report on the application of apertureless THz near-field microscopy for sensing charge carriers in semiconductors. This technique allows for contactless probing of electron concentrations on a micrometer scale. Experimental data and model calculations indicate that as few as about 5000 electrons can be detected in a GaAs structure. (c) 2006 American Institute of Physics.
