摘要

In this work, the electrochemical behaviors of tin selenide precursor ions are studied by cyclic voltammetry in low-temperature molten salt. Based on these results, SnSe film are synthesized by molten salt electrolysis. The effects of reaction conditions on the morphology and crystal structure of the deposited samples are discussed. The results show that the deposition voltage effectively regulates the growth of lattice plane of SnSe. SnSe films with preferred orientation of (111) and (400) are obtained. Compared with aqueous electrolysis, molten salt electrolysis enables easier control of the ion diffusion rate, resulting in different preferred crystal plane growth.
