AbstractThe treatment of Ge(100) in an aqueous ammonium sulfide solution is investigated by means of x-ray photoelectron spectroscopy, Auger electron spectroscopy, low-energy electron diffraction, scanning electron microscopy, and atomic force microscopy. This treatment is shown to produce an S-passivated Ge(100)-(1×1) surface, where the S atoms appear to be bridge bonded to the Ge atoms. Desorption of the S is observed to occur between 460 and 750 K and results in a Ge(100)-(1×1) surface with a surface morphology similar to that of the initial sample.
