Keysight Technologies Humidity-dependent Surface Chemistry Studied by Keysight 7500 Atomic Force Microscopy Application Note Introduction represents the calcite surface. In order to demonstrate that the hydroxylation One of the key advantages of atomic reaction of calcite surfaces can be force microscopy (AFM) over other captured from an AFM point of view, members within the microscopy family a freshly cleaved CaCO 3 sample was is its capability of being operated under placed into the AFM chamber for a different environments. Particularly, certain period of time while the relative a complete control of the relative humidity inside was maintained at a humidity (RH) in air surrounding the preferable level. Then it was checked localized tip/sample region is highly by an AFM. Showing in Figure 1 is AFM Topography desired for an AFM as it will render topography of the resulting surface. In users a valuable means to address addition to those surface features such a lot of humidity-dependent issues. as the smooth domains and straight step The Keysight Technologies, Inc. edges that are intrinsic to the calcite 7500 AFM system is comprised of a material, some newly formed protrusion sealed environmental chamber with islands are clearly resolved. Three eight accessible ports and a build-in selected examples are highlighted using humidity senor, thus allowing the in situ the dotted white circles. Such surface monitoring and control of the RH during morphologies are not observed on those AFM measurements. In this application calcite samples when they were imaged brief, investigations of the inluence of immediately after transferring into the humidity on selected surface reactions
