Topotactical growth of indium sulfide by evaporation of metal onto molybdenite

Abstract The growth of In 2 S 3 and InS by vacuum evaporation of indium metal on the surface of molybdenite has been observed in the initial stage of film growth. By the increment of In 2 S 3 particle size, InS was also produced. By the increase of the film thickness to more than 20 nm, indium crystal predominately grew. The topotactic relations among the substrate and sulfide are as follows: 0 0 0 1 MoS 2 ∥ 1 1 0 In 2 S 3 , [1 0 1 0] MoS 2 ∥[1 1 1] In 2 S 3 or 0 0 0 1 MoS 2 ∥ 1 1 0 In 2 S 3 , [1 0 1 0] MoS 2 ∥[1 0 0] In 2 S 3 .
