A novel AFM/STM/SEM system

Abstract

An atomic force/scanning tunneling (AFM/STM) microscope intended for operation inside a scanning electron microscope (SEM) is described. This AFM/STM/SEM system enables us to image a sample conventionally by SEM as well as to investigate the local surface topography by AFM or STM. This device incorporates a new method for monitoring AFM cantilever deflection that utilizes the focused electron beam of the SEM.
