    A GaS thin film has been formed epitaxially on GaAs(100) using a photoassisted growth-etching reaction between H2S and the GaAs substrate. In the reaction, the growth of GaS is accomplished via the replacement of As in the GaAs lattice by the photochemically generated S atom, while As is etched...
