  • Patent number: 9296622
    Abstract: Disclosed herein are indium-tin-oxide nanoparticles and a method for continuously producing precipitated indium-tin nanoparticles having a particle size range of substantially from about 10 nm to about 200 nm and a substantially consistent ratio of indium to tin in the resultant nanoparticles across the duration of the continuous process, based on the ratio of indium to tin in a seeding solution. The method comprises preparing intermediate indium and tin compounds of the general formula [M(OH)xCy], where M represents the indium or tin ionic component of indium or tin salts, C represents the cationic component of indium or tin salt(s), x is a number greater than 0 and y=[M*valance?x]/C* valance in the seeding solution. The intermediate compounds are continuously precipitated with a base solution in a reaction vessel initially having a solvent contained therein. The method also provides a means for controlling the shape of the resultant nanoparticles.

  • Patent number: 8164089
    Abstract: Electronic devices, such as organic thin film transistors, with improved mobility are disclosed. The semiconducting layer comprises layers or striations of an organic semiconductor and graphene, including alternating layers/striations of such materials. The organic semiconductor and graphene layers interact well together because both materials form lamellar sheets. The presence of graphene enhances mobility by correcting molecular packing defects in the organic semiconductor layers, and the conductivity of graphene can be controlled. Finally, both materials are flexible, allowing for flexible semiconductor layers and transistors.
