Description

technical field [0001] The invention relates to an atomic force microscope probe used for nanometer detection of micro / nano materials and devices, in particular to a liquid-phase atomic force microscope probe. Background technique [0002] With the rapid development of nanotechnology, ultra-high resolution instruments such as scanning tunneling microscope (STM) and atomic force microscope (AFM) have become indispensable and important tools for nanotechnology workers. Among them, the application of AFM is more extensive. AFM is a high-precision, high-sensitivity surface observation and testing instrument, suitable for conductive and non-conductive samples, and capable of operating in most corrosive solutions and gases [4.5]. These superior properties not only make it possible to obtain data about the surface structure, but also directly and in real time observe and obtain valuable dynamic information of surface changes at the atomic or nanometer lev...
