Abstract
- ZnSnN<subscript>2</subscript> has potential applications in photocatalysis and photovoltaics. However, the difficulty in preparing nondegenerate ZnSnN<subscript>2</subscript> hinders its device application. Here, the preparation of low-electron-density nanocrystalline ZnSnN<subscript>2</subscript> and its device application are demonstrated. Nanocrystalline ZnSnN<subscript>2</subscript> was prepared with reactive sputtering. Nanocrystalline ZnSnN<subscript>2</subscript> with an electron density of approximately 10<superscript>17</superscript> cm<superscript>−3</superscript> can be obtained after annealing at 300 °C. Nanocrystalline ZnSnN<subscript>2</subscript> is found to form Schottky contact with Ag. Both the current I vs. voltage V curves and the capacitance C vs. voltage V curves of these samples follow the related theories of crystalline semiconductors due to the limited long-range order provided by the crystallites with sizes of 2–10 nm. The I−V curves together with the nonlinear C<superscript>−2</superscript>−V curves imply that there are interface states at the Ag-nanocrystalline ZnSnN<subscript>2</subscript> interface. The application of nanocrystalline ZnSnN<subscript>2</subscript> to heterojunction solar cells is also demonstrated. [ABSTRACT FROM AUTHOR]
