  1. Unraveling the Sinuous Grain Boundaries in Graphene

    Zhuhua Zhang, Yang Yang, Fangbo Xu, Luqing Wang and Boris I. Yakobson

    Article first published online: 31 OCT 2014 | DOI: 10.1002/adfm.201403024

    Grain boundaries are intrinsic to polycrystalline graphene and often exhibit diversely sinuous structures. Here, it is revealed that the sinuous grain boundaries are energetically preferred over the straight forms when the grain division is asymmetric, and their well-defined configurations agree well with experimental observations. Importantly, such grain boundaries show improved strength as well as uniformly semiconducting electronic transport behavior.

    Using Polymer Electrolyte Gates to Set-and-Freeze Threshold Voltage and Local Potential in Nanowire-based Devices and Thermoelectrics

    Sofia Fahlvik Svensson, Adam M. Burke, Damon J. Carrad, Martin Leijnse, Heiner Linke and Adam P. Micolich

    Article first published online: 31 OCT 2014 | DOI: 10.1002/adfm.201402921

    A nanoscale patterned polymer electrolyte gate is used to “freeze in” ionic charge environments at low temperatures around an indium arsenide nanowire. The low thermal conductivity of the local wrap-gate allows side-by-side investigations of the conductance and thermoelectric properties of the gated nanowire segment over a series of biases applied to the polymer electrolyte.

  3. Surface Directed Phase Separation of Semiconductor Ferroelectric Polymer Blends and their use in Non-Volatile Memories

    Albert van Breemen, Tomasz Zaba, Vsevolod Khikhlovskyi, Jasper Michels, Rene Janssen, Martijn Kemerink and Gerwin Gelinck

    Article first published online: 29 OCT 2014 | DOI: 10.1002/adfm.201401896

    3D morphology control in polymer resistive memories by surface directed phase separation of semiconductor ferroelectric blends is presented. Full 3D numerical simulation of the surface-controlled de-mixing process provides insight in the ability of the substrate pattern to direct the phase separation. Pattern replication on a cm-scale is achieved leading to enhanced functional device performance.

  4. Comparison of Two D−A Type Polymers with Each Being Fluorinated on D and A Unit for High Performance Solar Cells

    Jea Woong Jo, Seunghwan Bae, Feng Liu, Thomas P. Russell and Won Ho Jo

    Article first published online: 27 OCT 2014 | DOI: 10.1002/adfm.201402210

    Two types of fluorinated D−A polymers with each being fluorinated on D and A unit are designed and synthesized. The D−A polymer with fluorinated D unit exhibits well-developed fibril network, low bimolecular recombination and high hole mobility, leading to a high PCE of 7.10%, which is higher than the PCE (6.41%) of the polymer with fluorinated A unit.

  5. Graphene-Directed Supramolecular Assembly of Multifunctional Polymer Hydrogel Membranes

    Yufei Wang, Sheng Chen, Ling Qiu, Kun Wang, Huanting Wang, George P. Simon and Dan Li

    Article first published online: 27 OCT 2014 | DOI: 10.1002/adfm.201402952

    A versatile approach to the fabrication of multifunctional polymer hydrogel membranes is demonstrated by exploiting the unique micro-corrugated 2D configuration of chemically converted graphene, its self-assembly behavior and rich supramolecular interactions. A range of water soluble polymers can be readily processed into such membranes with tunable nanostructures to suit a variety of potential applications.
