Structure of high-index GaAs surfaces – the discovery of the stable GaAs (2 5 11) surface
We present a brief overview of surface structures of high-index GaAs surfaces, putting emphasis on recent progress in our own laboratory. By adapting a commercial scanning tunneling microscope (STM) to our mol...

Thermal etching of GaAs (1 1 3) surfaces
We discuss scanning electron micrographs and atomic force microscope images of thermally etched GaAs(1 1 3) surfaces. The GaAs(1 1 3)A and GaAs(1 1 3)B surfaces are compared. The polarity of the surface leads ...
