Solar Cells: Understanding the Charge-Transfer State and Singlet Exciton Emission from Solution-Processed Small-Molecule Organic Solar Cells (Adv. Mater. 43/2014).

World-record-performing bulk-heterojunction (BHJ) small molecule solar cells are realized by careful optimization of their solid-state morphology. These BHJ films are transformed from an intimate mixture of the donor and acceptor phases to films with well-defined donor crystallites. In addition to correlating with a high photovoltaic response, the donor crystallites also appear to be linked with the emergence of donor singlet electroluminescence at low applied biases, where only charge-transfer-state emissi...

Organic Field-Effect Transistors: Dramatic Inversion of Charge Polarity in Diketopyrrolopyrrole-Based Organic Field-Effect Transistors via a Simple Nitrile Group Substitution (Adv. Mater. 43/2014).

A record-breaking high electron mobility (up to 7.0 cm(2) V(-1) s(-1) ) is demonstrated with a diketopyrrolopyrrole (DPP)-based semiconductor (PDPP-CNTVT), of which a vinylene unit is simply incorporated with only one nitrile group, as described by Y.-H. Kim, Y.-Y. Noh, as described by S.-K. Kwon, and co-workers on page 7300. Both the strong electron-withdrawing property of the nitrile group and its low steric-hindrance effect in the conjugation backbone can help the hole-dominant polymer (PDPP-TVT) to be c...

Light-Emitting Diodes: An Organic Down-Converting Material for White-Light Emission from Hybrid LEDs (Adv. Mater. 43/2014).

Combining a yellow-emitting organic material with a blue-emitting inorganic light-emitting device (LED) provides a hybrid white-light LED. This approach, demonstrated by R. W. Martin, P. J. Skabara, and co-workers on page 7290, couples very efficient blue emission with the flexibility, fast modulation speed, and cost effectiveness of the organic material. For the latter, BODIPY is used as the emitter and linked to a conjugated unit designed to efficiently absorb a suitable fraction of the blue light.

Tailoring Transient-Amorphous States: Towards Fast and Power-Efficient Phase-Change Memory and Neuromorphic Computing.

A new methodology for manipulating transient-amorphous states of phase-change memory (PCM) materials is reported as a viable means to boost the speed, yet reducing the power consumption, of PC memories, and is applicable to new forms of PCM-based neuromorphic devices. Controlling multiple-pulse interactions with PC materials may provide an opportunity towards developing a new paradigm for ultra-fast neuromorphic computing.

Liquid-Type Cathode Enabled by 3D Sponge-Like Carbon Nanotubes for High Energy Density and Long Cycling Life of Li-S Batteries.

High energy density and long term stability of Li-S batteries are achieved by employing a 3D sponge-like carbon nanotube cathode and a liquid-type polysulfide catholyte. Carbon nanotubes provide not only excellent electron pathways and polysulfide reservoirs but can also be used as a standalone cathode without current collectors, which greatly alleviates problems arising from insulating sulfur and polysulfide shuttles as well as remarkably increases the energy density.

M. Ullah, E. B. Namdas, and co-workers present on page 6410 the first all-solution-processed hybrid light-emitting transistors, and demonstrate the effectiveness of their operation with three organic emissive materials. This approach involves the fabrication of a bilayer device structure using a solution of organic emissive material, and a sol-gel of zinc tin oxide. The use of nonplanar contacts is also demonstrated in this study as playing a crucial role in the enhanced optoelectronics characteristics.

Twelve-pointed graphene grains are controllably fabricated on a liquid Cu surface by ambient pressure chemical vapor deposition, as described by G. Yu and co-workers on page 6423. These novel-shaped grains are characterized as single-layer and single-crystalline. The distinct nature of the alternating edge types (zigzag and armchair edges in sequence) in such a grain may result in their promising application in spintronics and other areas.

Han and co-workers report on page 6394 the clean, fast, and inexpensive direct transfer of large-area monolayer CVD graphene from Cu foil to various substrates such as PET, PDMS, and glass using a mechano-electro-thermal (MET) process. This process leads to ultraconformal contact between the graphene and the target substrate, which increases the higher adhesion energy of the graphene to the substrate over Cu foil. This transferred graphene presents both excellent quality (with no residues or defects) ...

Spintronic Functionality of BiFeO3 Domain Walls.

Anisotropic magnetoresistance at the BiFeO3 domain walls has been observed thanks to the realization of micro-devices that allow the direct magneto-transport characterization of the domain-walls. Anisotropic magnetoresistance of ferromagnetic metals has been a pillar in spintronic technology, and now it is evidenced at the conductive domain walls of an insulating ferroelectric material, which implies that domain walls become an electrically tunable nanospintronic object.

Metal Nanowire Networks: The Next Generation of Transparent Conductors.

There is an ongoing drive to replace the most common transparent conductor, indium tin oxide (ITO), with a material that gives comparable performance, but can be coated from solution at speeds orders of magnitude faster than the sputtering processes used to deposit ITO. Metal nanowires are currently the only alternative to ITO that meets these requirements. This Progress Report summarizes recent advances toward understanding the relationship between the structure of metal nanowires, the electrical and optic...
