Embodiment

[0023] Embodiment: a kind of preparation method of two-dimensional organic rubrene single crystal nanosheet of hundred microns, such as Figure 1-Figure 7 Shown, described preparation method is:

[0024] Step 1. Preparation: prepare some ordinary silicon wafers, clean them with alcohol, and dry them with nitrogen for later use; grind rubrene into powder for later use;

[0025] Step 2. Select two silicon wafers to form the evaporation unit. The size of the two silicon wafers is 1.5cm×1.5cm. The two silicon wafers are separated by four glass sheets of equal thickness. The allowable interval between the two silicon wafers is 30-60 microns, during evaporation, the above-mentioned evaporation unit is placed on a heating platform for heating, wherein the lower layer of silicon chip is the evaporation source carrier for carrying the evaporated rubrene powder, and the upper layer of silicon The sheet is the deposition substrate, which is used to carry the two-dimensional organic sing...

Description

technical field [0001] The invention belongs to the technical field of preparation of two-dimensional organic single-crystal nanosheets of hundred micrometers, and in particular relates to a preparation method of two-dimensional organic rubrene single-crystal nanosheets of one hundred micrometers. Background technique [0002] Semiconductor low-dimensional micro-nanostructures (such as nanowires, nanosheets, etc.) have the ability to transmit and regulate light waves on a sub-wavelength scale, so they have broad application potential in the fields of organic light-emitting, micro-nano lasers, and optical waveguides. Nano-dimensional single crystals (such as one-dimensional nanowires and two-dimensional nanosheets) have light processing capabilities such as light capture, regulation, and transport. Therefore, these nanoscale single crystals constitute the basic building blocks of optical integrated circuits. In the industry, a "top-down" approach is usually used to prepare i...
