In order to realise our predictions experimentally, two key challenges will need to be addressed, viz. synthesis/stability and optimising the electrical properties. π SnS and SnSe have been prepared in nanoparticulate and thin-film forms with techniques including chemical bath deposition (CBD), solution synthesis, spray pyrolysis, and aerosol-assisted chemical vapour deposition (AACVD). A number of experiments have examined thermal stability, with the consensus that π SnS transforms to the Pnma phase on heating to ≈600 K or higher. If the stability "window" cannot be widened, π SnS and SnSe could only be used for low-temperature applications.
