摘要：

Surfaces of p-GaAs(100) electrodes in HCl solution were studied by using an electrochemical atomic force microscope with atomic resolution. Truncated pyramids of relatively uniform size (50-100 nm square) were formed if p-GaAs(100) was anodically polarized. An atomic arrangement of (100)-(1 X 1) structure was observed on the terrace of the truncated pyramid when the electrode was kept in the potential region where no current flowed.
