    1. Organic Electronic Interface Devices: Light- and Touch-Point Localization using Flexible Large Area Organic Photodiodes and Elastomer Waveguides (Adv. Mater. 34/2009)

      Robert Koeppe, Petr Bartu, Siegfried Bauer and N. Serdar Sariciftci

      Article first published online: 3 SEP 2009 | DOI: 10.1002/adma.200990128

      Thumbnail image of graphical abstract

      The inside cover shows a flexible, large-area, position-sensitive organic photodetector used as an input device for a desktop computer. R. Koeppe et al. show the assembly of such a device with a photodiode based on a blend of Zn-phthalocyanine and C60 with low conductivity electrodes on p. 3510. The current drop across the electrodes easily allows for the calculation of the position of a localized light signal impinging on the position-sensitive photodetector. By adding an additional elastomer layer with embedded LEDs, the device can also be used as flexible touchpad.

      Direct, charge-mediated magnetoelectric coupling is demonstrated in a heterogeneous multiferroic that takes advantage of the sensitivity of a strongly correlated magnetic system to competing electronic ground states. Using magneto-optic Kerr effect magnetometry, we observe large magnetoelectric coupling in ferroelectric/lanthanum manganite heterostructures, resulting in control of the magnetic state by means of an applied electric field, as illustrated in the figure.

      Bilayered Pb(Zr(1–x),Tix)O3 ferroelectric thin film heterostructures show complex ferroelastic nanodomain patterns. These ferroelastic nanodomains exist only in the upper layer, and hence are able to move under the application of an external electric field. Quantitative analysis reveals an enhanced piezoelectric coefficient of ≈220 pm V−1, rendering them attractive for a variety of electromechanical devices.

      Noble metal nanostructures can enhance absorption in thin-film solar cells by simultaneously taking advantage of i) high near-fields surrounding the nanostructures close to their surface plasmon resonance frequency and ii) coupling to waveguide modes. We develop basic design rules for the realization of broadband absorption enhancements for such structures.

    2. Light- and Touch-Point Localization using Flexible Large Area Organic Photodiodes and Elastomer Waveguides (pages 3510–3514)

      A novel inorganic–organic hybrid nanocomposite is formed in situ using a simple and straightforward method. Conjugate of short interfering RNA (siRNA) duplex with poly(ethylene glycol) via a disulfide linkage (PEG–SS–siRNA) is demonstrated to regulate the crystal growth of calcium phosphate (CaP), yielding a monodispersed nanocomposite. The resultant nanocomposite can be utilized as nanocarriers for siRNA delivery.
