Problems solved by technology

However, one of the biggest difficulties in the preparation of micro-nanostructures by the solution method is that it is difficult to control the flow of the solution, especially when the solution flows on the surface of the micro-nanostructures, it is easy to cause heterogeneous structures to form chaotic connections at the junctions.

Abstract

The invention discloses a printing method of a functional micro nano heterostructure. The method comprises the following steps of: 1, uniformly spreading organic-phase nano material assembling liquidon the surface of a silicon pillar template, then covering a substrate on the silicon pillar template, and enabling a solvent in the organic-phase nano material assembling liquid to be volatilized, soas to form a point array structure which is regular in arrangement and formed by deposition of a nano material on the substrate; and 2, injecting water-phase nano material assembling liquid onto thesilicon pillar template, and enabling water in the water-phase nano material assembling liquid to be volatilized, so that the nano material is deposited on the substrate in a regular ordered line array structure, and finally, the point-line connection micro nano heterostructure is formed on the substrate. The printing method can implement large-area printing of the heterostructure on the substrate, so that the heterostructure has potential application value in the aspects of a micro nano electronic circuit, an optical element, biological detection and the like.

Description

technical field [0001] The invention relates to a printing method of a functional micro-nano heterogeneous structure. Background technique [0002] Functional dot-line micro-nanostructures are the basic functional units that constitute many optical components, microelectronic circuits, and sensors, and have great potential application value in industrial applications. In particular, the dot-line micro-nano structure is connected in a lateral manner, which can reasonably combine the properties of the functional dot-line micro-nano structure, and provides physical characteristics that a single functional dot-line micro-nano structure does not have. In the connection of dot-line micro-nano structures, the connection mode of dot-line micro-nano units is particularly important. The novel interfaces appearing at the junctions of dot-line micro-nanostructures have attracted much attention in the study of heterostructures in recent years, providing many innovative functions for het...
