Materials for devices are materials employed in devices because of their particular properties, such as electrical, thermal, magnetic, mechanical, ferroelectric or piezoelectric properties. Examples of materials for devices are polymers, oxides, semiconductors and liquid crystals.
Single-crystal black phosphorus nanoribbons have been grown through chemical vapour transport, using black phosphorus nanoparticles as seeds. The nanoribbons orient exclusively along the zigzag direction and have good semiconductor properties that render them suitable for use as channel material in field-effect transistors.
Polycrystalline films of the non-toxic element bismuth exhibit a room-temperature surface nonlinear Hall effect, which could make devices based on topological quantum effects more practical.
3D-printed glass holds great potential. However, it is challenging to control both the dimension and the resolution of the printed material. Here, authors present a one-photon 3D printing approach to produce high-performance fused silica glass with sub-micron resolution and millimetric dimensions.
The device’s electroluminescence efficiency is vital to reduce non-radiative voltage losses and boost organic solar cell performance. Here, the authors demonstrate that this efficiency is influenced not only by the decay of charge transfer states but also by the dissociation of singlet states.
Mechanoluminescence enables sensing applications of mechanical stimuli. Here, the authors reveal the importance of interfacial triboelectricity to this phenomenon in inorganic-organic composite materials.
