我们描述了一种利用扫描近场微波显微镜提取地形信息的技术。通过监测系统谐振频率的移动,我们得到了均匀导电金属表面的定量形貌图像。在9.572μ频率下,我们的技术允许在30μm的间隔下进行约55 nm的高度分辨。我们展示了不均匀的导电样品的地形图像,并将系统的高度响应和灵敏度与理论预期进行了比较。
We describe a technique for extracting topographic information using a scanning near-field microwave microscope. By monitoring the shift of the system’s resonant frequency, we obtain quantitative topographic images of uniformly conducting metal surfaces. At a frequency of 9.572 GHz, our technique allows a height discrimination of about 55 nm at a separation of 30 μm. We present topographic images of uneven, conducting samples and compare the height response and sensitivity of the system with theoretical expectations.
