Abstract:
본 발명은 균일하고 잘 정렬된 발광물질로 이루어진 나노 구조물을 제조하여 이를 발광소자에 적용함으로써, CCFL이나 LED와 같은 종래의 후면광 유닛에 비해, 두께를 줄이고 소비전력을 낮추며 동시에 광원의 균일성을 우수하게 할 수 있는 광원용 구조물과 이를 이용한 광원의 제조방법에 관한 것이다. 본 발명에 따른 광원용 구조물의 제조방법은, 이중공중합체(DBC)로 나노패턴을 형성한 후, 이를 전극으로 사용하는 금속층에 전사하여, 금속층에 형성된 나노패턴을 마스크로 하여 발광물질의 나노구조를 형성함으로써, 종래에 비해 우수한 광원을 제공할 수 있도록 하는 것을 특징으로 한다. 후면광, 디스플레이, ZnO
Abstract:
PURPOSE: A method for doping a zinc oxide is provided to improve the electrical conductivity by increasing the concentration of a carrier while the mobility of the carrier is maintained. CONSTITUTION: A zinc oxide forming part(10), which includes a first bubbler, a first inert gas tank, and a first mask flow controller(13), forms a transparent conductive zinc oxide thin film. A doping part(20) is arranged to be symmetric to the zinc oxide forming part. With respect to the transparent conductive zinc oxide thin film, one or more elements from the IIIA family is doped with the zinc of the zinc oxide and one or more elements from the VIIA family is doped with the oxygen of the zinc oxide.
Abstract:
Genes are provided to be used for preparing a transformant with heavy metal, salt or drought resistance which is used for rehabilitation, developing a safe plant capable of preventing second contamination caused by soil loss and absorbing heavy metals less than a wild-type plant and a novel species capable of contributing agriculture and environment of land reclamation or dried area due to improved salt or drought resistance. A gene altering heavy metal and salt resistance and accumulation capacity includes a sequence encoding a biomembrane passage protein where 4 similar biomembrane passage domains are repeated 5 times. A recombinant vector includes the gene which is linked to be controlled by transcription and translation controlling factors, the factors expressible in a plant. The recombinant vector further comprises a gene altering the heavy metal, salt or drought resistance including a sequence encoding an ABC transport protein where 6 biomembrane passage domains and ATP binding domains are repeated 2 times and a gene having the salt or drought resistance selected from the sequences encoding proteins having a GTP binding domain and a CaaL domain(Geranylgeranylation motif). A transformant is transformed by the recombinant vector. A method for preparing an environment purifying plant with improved heavy metal resistance or accumulation capacity or a safe plat with lowered heavy metal absorption comprises the steps of: (a) preparing an expression cassette including the gene linked to be controlling by the transcription and translation controlling factors; (b) preparing the recombinant vector including the expression vector; and (b) introducing the recombinant vector into a plant cell or a plant tissue. Further, the heavy metal is selected from a group consisting of arsenic, antimony, lead, mercury, cadmium, chrome, tin, zinc., barium, bismuth, nickel, cobalt, manganese, iron, cupper, vanadium and a mixture thereof.
Abstract:
PURPOSE: A method of manufacturing a structure for light source and a method of manufacturing a light source using the same are provided to reduce the thickness and power consumption by applying nanostructure of uniform and aligned light emitting material to a light emitting device. CONSTITUTION: A metal layer is formed on the top of a substrate on which an oxide layer is formed(1). A nanotemplate formed with the nano pattern is formed on the metal layer. The nano pattern is transferred to the metal layer by etching the metal layer. The nanotemplate is removed. A nano structure is formed by growing the light emitting material in a space of the oxide layer. The metal layer and the nanostructure are separated from the substrate by eliminating the oxide layer.
