- The Origin of Excellent Gate-Bias Stress Stability in Organic Field-Effect Transistors Employing Fluorinated-Polymer Gate Dielectrics
Jiye Kim, Jaeyoung Jang, Kyunghun Kim, Haekyoung Kim, Se Hyun Kim and Chan Eon Park
Article first published online: 29 SEP 2014 | DOI: 10.1002/adma.201402363
Tuning of the energetic barriers to charge transfer at the semiconductor/dielectric interface in organic field-effect transistors (OLEDs) is achieved by varying dielectric functionalities. Based on this, we demonstrate the correlation between the magnitude of the energy barrier and the gate-bias stress stability of the OFETs, and reveal the origin of the excellent device stability of OFETs employing fluorinated dielectrics.

A self-adhesive laminate solar cell electrode is presented based on a metal grid embedded in a polymer film (x-y conduction) and contacted with the active layer using a pressure sensitive adhesive containing a very low quantity (1.8%) of organic conductor which self-organizes to provide z conduction to the grid. This ITO free material performs in an identical fashion to evaporated gold in high efficiency perovskite solar cells.
- Band-Selective Infrared Photodetectors with Complete-Composition-Range InAsxP1-x Alloy Nanowires

Article first published online: 25 SEP 2014 | DOI: 10.1002/adma.201402945
Band-selective infrared photodetectors (PDs) are constructed with InAsxP1-x alloy nanowires from the complete composition range (0 ≤ x ≤ 1) achieved by a new growth route combining the vapor–liquid–solid mechanism with an additional ion-exchange process. Increasing the composition x value from 0 to 1 in the PDs allows the peak response wavelength to be gradually tuned from ca. 900 to ca. 2900 nm.
- Biocompatible Nanogenerators through High Piezoelectric Coefficient 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 Nanowires for In-Vivo Applications

The lead-free 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 (BZT-BCT) nanowires with a high piezoelectric coefficient are synthesized and the nanogenerators (NG) composed of them are successfully developed. The studied in vitro and in vivo biocompatibility of the NGs shows great potential for their application as in vivo power sources.
- Stretchable Energy-Harvesting Tactile Electronic Skin Capable of Differentiating Multiple Mechanical Stimuli Modes

Article first published online: 25 SEP 2014 | DOI: 10.1002/adma.201402574
The first stretchable energy-harvesting electronic-skin device capable of differentiating and generating energy from various mechanical stimuli, such as normal pressure, lateral strain, bending, and vibration is presented. A pressure sensitivity of 0.7 kPa-1 is achieved in the pressure region <1 kPa with power generation of tens of μW cm-2 from a gentle finger touch.
