| titleOfInvention | Preparation method of two-dimensional nano SnSe2 crystal material |
| abstract | The invention discloses a preparation method of a two-dimensional nano SnSe2 crystal material, which can deposit a SnSe2 crystal with required thickness on a substrate by using a simple substance selenium and tin halide by a chemical vapor deposition process, wherein the deposition equipment is a horizontal tube furnace which is sequentially provided with an upstream low-temperature region, a central temperature region and a downstream low-temperature region, the simple substance selenium and tin halide are respectively independently and closely arranged in the upstream low-temperature region, and the substrate is arranged in the downstream low-temperature region; by utilizing the temperature difference of different temperature regions, the simple substance selenium steam and tin halide steam are formed on the upstream low-temperature region; and the simple substance selenium steam and tin halide steam react to generate SnSe2, and the SnSe2 is taken into the downstream temperature region through a deposition carrier gas and deposits on the substrate to obtain the two-dimensional nano SnSe2 crystal material. The method can be utilized to prepare the two-dimensional nano SnSe2 crystal material with uniform thickness and consistent shape, and the two-dimensional nano SnSe2 crystal material is 3-10 atomic layers thick (1-3 layers of SnSe2) and has wide application prospects in electronic devices. |
