Iodine adsorption (or reaction) on atomically-flat H-terminated Si(111) surfaces in 7.1 M HI and 7.1 M HI+0.05 M I2 was investigated by X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). XPS measurements showed that iodine was adsorbed gradually with time when immersed in 7.1 M HI, and rapidly and in a larger quantity when immersed in 7.1 M HI/0.05 M I2. AFM inspection showed that circular dot-like clusters were formed initially in both the HI and HI/I2 solutions. However, for the case of 7.1 M HI solution, dot-like clusters, located near steps, grew with time only in particular directions of threefold symmetry of Si(111), resulting in ordered wire-like clusters. For the case of HI/I2 solution, the circular dot-like clusters were distributed randomly on terraces and steps even after prolonged immersion, with no formation of any ordered clusters.
