As you can tell, you can only image conductive samples A makeshift probe holder ... The reason for the high-speed micro is the need to control the scanning signals based on the measured tunnelling ...

A bias voltage applied between the tip and the sample causes electrons to tunnel across the ... allowing the device to image surfaces with atomic precision. Scanning Tunneling Microscopy is a subset ...

For maximum resolution in a scanning tunneling microscope (STM), an extremely sharp metallic tip is required, which serves as the point through which the STM “scans” a sample. A blunt tip reduces STM ...
