抜粋

The capability of a new AFM-based apparatus named microwave atomic force microscope (M-AFM) which can measure the topography and electrical information of samples simultaneously was investigated. Some special samples with different thicknesses of dielectric film (SiO2) which plays the role of oxide layer creating on the material surface were fabricated. The measurement of electrical properties of materials under the oxide layer by the M-AFM was studied. The results indicate that the M-AFM can lead the microwave signal penetrate the oxide film (SiO2) with a limited thickness of 60 nm and obtain the electrical information of underlying materials.
