摘要： An object is to provide a material suitably used for a semiconductor included in a transistor, a diode, or the like. Another object is to provide a semiconductor device including a transistor in which the condition of an electron state at an interface between an oxide semiconductor film and a gate insulating film in contact with the oxide semiconductor film is favorable. Further, another object is to manufacture a highly reliable semiconductor device by giving stable electric characteristics to a transistor in which an oxide semiconductor film is used for a channel. A semiconductor device is formed using an oxide material which includes crystal with c-axis alignment, which has a triangular or hexagonal atomic arrangement when seen from the direction of a surface or an interface and rotates around the c-axis.

摘要： A silicon-based negative electrode composite material. Zinc and tin are doped in a silicon-based negative electrode material. The presence of a tin and zinc alloy improves the conductivity of the silicon-based material, and a coated carbon shell has pores, facilitating the infiltration of an electrolyte while improving the ionic conductivity and electronic conductivity of the material, so that the rate performance of the composite material is enhanced.

摘要： A high performance, lead free, Ag paste thermal interface material (TIM) for die attachment and substrate bonding in electronic packaging includes: (i) multiscale silver particles, (ii) metal-coated carbon nanotubes (CNTs), (iii) a polymer, and (iv) a liquid carrier. The multiscale silver particles and metal-coated carbon nanotubes, which function as hybrid filler components, are uniformly dispersed within the TIM composition. The sintered TIM exhibits high density, high mechanical strength, and high thermal conductivity. The components of the liquid carrier including the solvent, binder, surfactants, and thinner are completely evaporated or burned off during sintering. Sintering of the TIM can be conducted at a relatively low temperature, without or with very low (

摘要： Disclosed are a method of producing an electrochromic composition capable of diversifying colors, an electrochromic composition produced thereby, and an electrochromic device including the electrochromic composition. The electrochromic composition may be produced through a solution direct reaction using an electro-spray machine including two nozzles symmetrically inclined toward a central axis. The method may include preparing, respectively, a first coating composition comprising a first electrochromic compound and a second coating composition comprising a second electrochromic compound; loading, respectively, the first coating composition and the second composition into an electro-spray machine; spraying the first coating composition and the second coating composition under application of a voltage to the electro-spray device; and forming a electrochromic composition by reacting the first electrochromic compound with the second electrochromic compound during spraying.
