WebJan 20, 2024 · Scanning Probe Microscopy. There are two types of scanning probe microscope: the scanning tunneling microscope (STM) and the atomic force microscope (AFM). An STM uses a probe that is passed just above the specimen as a constant voltage bias creates the potential for an electric current between the probe and the specimen. WebJul 21, 2006 · A Key Shortcoming of Scanning Probe Procedures. The main drawback of scanning probe processes is the slow, serial technique through which they function. This feature has restricted their use specifically in laboratory applications that involve atom-at-a-time maneuvers.
