An atomic-resolution atomic-force microscope implemented using an optical lever

We present the first atomic‐resolution image of a surface obtained with an optical implementation of the atomic‐force microscope (AFM). The native oxide on silicon was imaged with atomic resolution, and ≊5‐nm resolution images of aluminum, mechanically ground iron, and corroded stainless steel were obtained. The relative merits of an optical implementation of the AFM as opposed to a tunneling implementation are discussed.
