It is difficult to convert SnS to n-type because acceptor-type defects are easily generated in SnS. In 2016, halogen-doped n-type SnS sintered bodies and single crystals were reported, but thin-film n-type SnS had not been reported so far, and it remained as a barrier to realize a homojunction device. In this study, Cl-doped SnS thin films with high n-type conductivity were realized by sputtering deposition with suppressing the generation of acceptor-type defects.
