Optoelectronic Devices: Controlling Polarization Dependent Reactions to Fabricate Multi-Component Functional Nanostructures (Adv. Funct. Mater. 24/2011)

Light Management with Nanostructures for Optoelectronic Devices.

Light management is of paramount importance to improve the performance of optoelectronic devices including photodetectors, solar cells, and light-emitting diodes. Extensive studies have shown that the efficiency of these optoelectronic devices largely depends on the device structural design. In the case of solar cells, three-dimensional (3-D) nanostructures can remarkably improve device energy ...

Materials and Wireless Microfluidic Systems for Electronics Capable of Chemical Dissolution on Demand (Adv. Funct. Mater. 92015)

Controlling the spin polarization of nanostructures on magnetic substrates.

It is shown that, by utilizing spin-selective quantum interference, the spin polarization of nanostructures deposited on a magnetic substrate with a surface state can be strongly modulated locally and energetically by an appropriate structural design. This finding is deduced from state-of-the-art ab initio calculations and interpreted within an analytical model. We present results for hexagonal...

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.
