Problems solved by technology
However, because the excitation and coupling of SP through electric field enhancement is relatively narrow, and it is easy to cause plasmon resonance to cause light absorption, so far there is no nanostructured metal that can be used in the entire visible light range simultaneously. Meet higher transmittance and greater conductivity

Abstract
A flexible transparent electrode, including an electrode unit, the electrode unit includes a metal substrate, and a dielectric material filled in the metal substrate, characterized in that: the electrode unit is a three-dimensional columnar unit with a continuous surface, and the dielectric material It includes two modules spaced apart from each other along the Z direction, each module includes at least one semi-elliptical cylinder, the axial direction of the semi-elliptic cylinder extends in the X-Y plane, the two ends of the semi-elliptic cylinder extend to the surface of the electrode unit, and the semi-elliptical cylinder The two axes of the semi-elliptical section of the elliptical cylinder extend along the X-Y plane and the Z direction respectively, and the semi-elliptical cylinders of the two modules are arranged head-to-head. The flexible transparent electrode not only has high electrical conductivity, which can reach the conductivity equivalent to silver film, but also has high transmittance, that is, the average transmittance can reach more than 70%, and the flexible transparent electrode structure can be customized according to the needs. Stacked or arranged in a desired shape, the applicable occasions are more extensive.
Description
Technical field [0001] The present invention relates to a transparent electrode. Background [0002] Transparent electrodes, an important part of various optoelectronic devices, have been widely used in sensors, displays, light-emitting diodes, solar cells and so on. With the development of science and technology, new high-performance optoelectronic devices require electrodes with higher conductivity and better transparency on this basis. [0003] However, the contradiction between light transmittance and conductivity hinders the development and research of transparent electrodes. Metals have freely moving electrons, thus providing greater conductivity, but this also makes it difficult for light to penetrate metals, because under the condition of an applied light field, free electrons will continue to be driven to the surface until the induced electric field generated by the induced charge is sufficient to counteract the applied electric field outside the metal. For the dielectr...
