    For the past forty years inorganic silicon and gallium arsenide semiconductors, silicon dioxide insulators, and metals such as aluminum and copper have been the backbone of the semiconductor industry. However, there has been a growing research effort in “organic electronics” to improve the semiconducting, conducting, and lightemitting properties of organics (polymers, oligomers) and ...

    In this paper we review recent progress in materials, fabrication processes, device designs, and applications related to organic thin-film transistors (OTFTs), with an emphasis on papers published during the last three years. Some earlier papers that played an important role in shaping the OTFT field are included, and a number of previously published review papers that cover that early period more... View full abstract»

    Organic-inorganic hybrid materials enable the integration of useful organic and inorganic characteristics within a single molecular-scale composite. Unique electronic and optical properties have been observed, and many others can be envisioned for this promising class of materials. In this paper, we review the crystal structures and physical properties of one family of crystalline, self-assembling... View full abstract»

  • Colloidal synthesis of nanocrystals and nanocrystal superlattices

    Publication Year: 2001, Page(s):47 - 56
    Cited by:  Papers (23)  |  Patents (32)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1203 KB)

    This paper provides an overview of the synthetic techniques used to prepare colloidal nanocrystals (NCs) of controlled composition, size, shape, and internal structure and the methods for manipulation of these materials into ordered NC assemblies (superlattices). High-temperature solution-phase synthesis (100–300°C) is followed by size-selective separation techniques in the preparati... View full abstract»

    Conjugated polymers in the nondoped and doped conducting state have an array of potential applications in the microelectronics industry. Conducting polymers are effective discharge layers as well as conducting resists in electron beam lithography, find applications in metallization (electrolytic and electroless) of plated through-holes for printed circuit board technology, provide excellent electr...

    Trapped and interfacial charges have significant impact on the performance of organic light-emitting devices (OLEDs). We have studied devices consisting of 20 nm copper phthalocyanine (CuPc) as the buffer and hole-injection layer, 50 nm N,N';-di(naphthalene-1-yl)-N,N'-diphenyl-benzidine (NPB) as the hole transport layer, and 65 nm tris(8-hydroxyquinolinato)aluminum (Alq3) as the electro...

  • STM-excited electroluminescence and spectroscopy on organic materials for display applications

    Publication Year: 2001, Page(s):89 - 100
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (540 KB)

    We present an overview of the current status of our work on scanning-tunneling-microscope-based (STM) spectroscopy and electroluminescence (EL) excitation to study the physical and electronic structure of organic materials used in organic light-emitting devices (OLEDs). By these means we probe the critical device parameters in charge-carrier injection and transport, i.e., the height of the barrier... View full abstract»

    The physical and chemical properties of tris(8-hydroxyquinolinato)aluminum (Alq3), one of the organic materials most commonly used as the light-emitting layer of OLEDs, and the interface with possible metal cathodes are investigated by means of first-principles computer simulations. A number of new insights have emerged from this study, and we emphasize the consequences of the propertie... View full abstract»
