Scanning tunneling microscopy of metal surfaces in air

We have constructed a scanning tunneling microscope (STM) for operation in air. We obtained surface images of a commercial titanium (Ti) plate, a barrier layer of anodic aluminum oxide (Al 2O 3) and platinum (Pt) fine particles supported on a TiO 2/Ti plate. We found the following results: (1) The r...

Description
Summary:We have constructed a scanning tunneling microscope (STM) for operation in air. We obtained surface images of a commercial titanium (Ti) plate, a barrier layer of anodic aluminum oxide (Al 2O 3) and platinum (Pt) fine particles supported on a TiO 2/Ti plate. We found the following results: (1) The resolution of our STM is better than 10 Å in air. (2) The surface image of the barrier layer has a somewhat complicated structure compared with hexagonal cells observed by SEM. (3) The surface of Pt fine particles is flat and shows a sharp and deep cliff down to the TiO 2/Ti plate.
