The reactions of I2 and Cl2 with InAs(001) were investigated with synchrotron-based soft-x-ray photoelectron spectroscopy and low-energy electron diffraction. I2 saturates the In-terminated InAs(001) surface, forming a well-ordered overlayer of InI, while As-terminated InAs(001) becomes disordered and forms both In and As iodides. Both the In- and As-terminated surfaces are disordered by Cl2 adsorption, forming InCl, InCl2, and As chlorides. The differences in the behavior of I2 and Cl2 are attributed primarily to the inability of InI2 to form on the outermost surface.
