Abstract

A microwave near field microscope has a novel microwave probe structure wherein the probing field of evanescent radiation is emitted from a sharpened metal tip instead of an aperture or gap. This sharpened tip, which is electrically and mechanically connected to a central electrode, extends through and beyond an aperture in an end wall of a microwave resonating device such as a microwave cavity resonator or a microwave stripline resonator. Since the field intensity at the tip increases as the tip sharpens, the total energy which is radiated from the tip and absorbed by the sample increases as the tip sharpens. The result is improved spatial resolution without sacrificing sensitivity. 17 figs.

High spatial resolution quantitative microwave impedance microscopy by a scanning tip microwave near-field microscope

Journal Article Gao, C; Wei, T; Duewer, F; ... - Applied Physics Letters

A recently developed scanning tip microwave near-field microscope has been improved to achieve a spatial resolution of 100 nm ({approximately}{lambda}/10{sup 6}). Furthermore, explicit calculations of the field distribution using a simplified model allow quantitative microscopy of dielectric properties for dielectric materials. A detection sensitivity of {delta}{var_epsilon}/{var_epsilon}{approximately}6{times}10{sup {minus}4} has been achieved. {copyright} {ital 1997 American Institute of Physics.}

Scanning tip microwave near-field microscope

Journal Article Wei, T; Xiang, X [Molecular Design Institute, Lawrence Berkeley National Laboratory, Berkeley, California 94720 (United States)]; Wallace-Freedman, W G; ... - Applied Physics Letters

A near-field microscope which operates in the rf/microwave frequency range is described. In this microscope, a scanning tunneling microscope (STM)-like tip rather than an aperture is used as a point-like evanescent field emitter. A spatial resolution of {approximately}5 {mu}m ({approximately}{lambda}/100000) is achieved in the current version. The design of the microscope as well as the principal factors which affect its performance are discussed. {copyright} {ital 1996 American Institute of Physics.}

Low temperature scanning-tip microwave near-field microscopy of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} films

Journal Article Takeuchi, I; Wei, T; Duewer, F; ... - Applied Physics Letters

We have explored the low temperature capability of a scanning-tip microwave near-field microscope to study superconductors. The shift in the quality factor of the microscope resonator can be used to obtain the temperature dependence of the surface resistance of a local region under the tip. Patterned YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} films were scanned at various temperatures and surface resistance mapping was performed with high spatial resolution at 1.2 GHz. Superconducting transitions at different positions on a film can be detected. Edge-region defects in wet-etched patterns were observed and were shown to be nonsuperconducting at microwave frequencies at 80 K. {copyright}more »« less
