Simultaneous Atomic Imaging of Atomic Force Microscopy and Scanning Tunneling Microscopy Using Metal Coated Cantilevers

Search this article

Abstract

Imaging of surface atoms with simultaneous measurement of noncontact atomic force microscopy (NC-AFM) and scanning tunneling microscopy (STM) is performed. Si cantilever coated with PtIr provides stable AFM/STM operations to obtain high spatial resolution images. AFM/STM measurements on Si(111)-(7×7), Ge(111)-c(2×8), and TiO2(110) surfaces are presented at room temperature. On the Ge(111)-c(2×8) surface, adatom and restatom sites which have the same atomic patterns are determined from dual bias AFM/STM measurements.
