The compound Sn-Se was prepared on p-Si(100) wafer by electrochemical atomic layer epitaxy under the condition of illumination. The cyclic voltammetry results indicated that the light could catalyze the deposition reaction. X-ray diffraction patterns indicate the growth of Sn-Se layers with (400) as the preferred orientation. The obtained microstructures were analyzed by scanning electron microscopy, atomic force microscopy and scanning tunneling microscopy . The X-ray diffraction data were shown in Fig. 1.
