  • Publication number: 20110210308
    Abstract: Disclosed are layers and patterns of nanowire or nanotube using a chemical self assembly for forming a semiconductor layer and a conductive layer of a thin film transistor by using a nanowire and/or nanotube solution and an diamine-based self-assembled monolayer (SAM) material. The Layers and patterns including layers and patterns of nanowire or nanotube using a chemical self assembly include: a substrate having a surface terminated with amine group (—NH2) by using a chemical self-assembled monolayer (SAM) material having at least one end terminated with amine group(—NH2); and a first nanowire or nanotube layer ionically coupled to the amine group (—NH2) of the surface of the substrate.

  • Publication number: 20100330750
    Abstract: A thin film transistor (TFT) including a nanowire semiconductor layer having nanowires aligned in one direction in a channel region is disclosed. The nanowire semiconductor layer is selectively formed in the channel region. A method for fabricating the TFT, a liquid crystal display (LCD) device using the TFT, and a method for manufacturing the LCD device are also disclosed. The TFT fabricating method includes forming alignment electrodes on the insulating film such that the alignment electrodes face each other, to define a channel region, forming an organic film, to expose the channel region, coating a nanowire-dispersed solution on an entire surface of a substrate including the organic film, forming a nanowire semiconductor layer in the channel region by generating an electric field between the alignment electrodes such that nanowires of the nanowire semiconductor layer are aligned in a direction, and removing the organic film.
