Preparation method and system of molybdenum disulfide (MoS2) nanodot array based on flexible substrate

Abstract

The invention discloses a preparation method and system of a molybdenum disulfide (MoS2) nanodot array based on a flexible substrate. The preparation method includes: cleaning the flexible substrate sputtered with an indium tin oxide film to obtain a clean substrate; drying the clean substrate to obtain a dry substrate; placing the dry and clean flexible substrate and MoS2 powder in a vacuum evaporator, heating and sublimating the MoS2 powder to condense the MoS2 powder on the dry and clean flexible substrate to obtain the MoS2 nanodot array. The preparation method or system of the MoS2 nano-dot array based on the flexible substrate directly uses the high vacuum evaporator to heat and evaporate the MoS2 powder onto the flexible substrate. A series of nano-dot arrays with controllable sizesand quantities can be prepared, and the finished product has high quality, and can be directly applied to the preparation of other flexible devices.

Description

technical field [0001] The invention relates to the field of nano-dot array preparation, in particular to a method and system for preparing a molybdenum disulfide nano-dot array based on a flexible substrate. Background technique [0002] In recent years, nanomaterials have been recognized by the world as new materials in the 21st century, and their research, preparation and application have become one of the most active scientific research fields today. Nanomaterials refer to materials with at least one dimension in the nanoscale range in three-dimensional space or materials composed of them as basic units. Nanomaterials can be divided into three categories according to the number of dimensions: (1) zero-dimensional, which refers to materials with three-dimensional dimensions in the nanoscale range, such as nanoparticles, atomic clusters, and quantum dots; (2) one-dimensional, which refers to materials with three-dimensional dimensions. Two-dimensional materials in the nan...
