An organic light emitting device having a photonic crystal structure and a manufacturing method thereof are provided. The organic light emitting device comprises: a substrate through which light passes; a photonic crystal layer formed on the substrate and having a photonic crystal structure; an intermediate layer formed on the photonic crystal layer and having a large refractive index compared with the photonic crystal layer; a first electrode layer formed on the intermediate layer; a light emitting layer formed on the first electrode layer and emitting light according to current flow; and a second electrode layer formed on the light emitting layer.

Organic light emitting device and manufacturing method thereof

Provided are a shape of a hierarchical structure, an engineering effect of the hierarchical structure according to the shape, an increasing method of the engineering effect, an application method of the hierarchical structure for novel material or parts, and a mass-manufacturing method of the hierarchical structure. The present invention relates to a hierarchical structure and a manufacturing method thereof, and includes a hierarchical structure in which at least one nano-object that has a characteristic length of a nanoscale region in an internal matrix is arranged in a predetermined pattern. According to the exemplary embodiments of the present invention, an excellent characteristic that is generated in a nanoscale region may be used in a structure of a macroscopic scale region, and structures that have different scales may be simply interconnected or interfaced regardless of the different scales.

Hierarchical structure and manufacturing method thereof

A method for forming a metal oxide thin film pattern using nanoimprinting according to one embodiment of the present invention includes: coating a photosensitive metal-organic material precursor solution on a substrate; pressurizing the photosensitive metal-organic material precursor coating layer to a mold patterned to have a protrusion and depression structure; forming the metal oxide thin film pattern by irradiating ultraviolet rays to the pressurized photosensitive metal-organic material precursor coating layer to cure it; and removing the patterned mold from the metal oxide thin film pattern.

Patterning method of metal oxide thin film using nanoimprinting, and manufacturing method of light emitting diode

The present invention relates to a micro/nano imprint lithography technique and in particular, to a stamp that is used in an UV-micro/nano imprint lithography process or thermal micro/nano imprint lithography process and a method for fabricating the stamp. The method for fabricating a stamp for micro/nano imprint lithography of the present invention includes i) depositing a thin film of diamond-like carbon on a substrate, ii) applying resist on the diamond-like carbon thin film, iii) patterning the resist, iv) etching the diamond-like carbon thin film by using the resist as a protective layer, and v) removing the resist.
