New plasmonic nanolaser is cavity-free

Proposed device could improve optical telecommunications.

Ionic crystals go 1D

Researchers in Japan have made the first truly one-dimensional diatomic chains inside CNTs.

Plasmonic nanoclusters could detect single molecules

Oligomers interact with light more strongly than isolated, uncoupled nanoparticles thanks to multiple plasmonic “hot spots” created in each cluster.

FinFETs go flexible

New soft-etching technique could allow for new applications in consumer electronics, such as in the emerging field of the “Internet of Things”.

Nanostructure toughens lightweight ceramics

Structuring a ceramic metamaterial makes it not only strong and light, but also robust enough to recover its original shape when deformed.

Graphene’s photothermoelectric effect for THz detection

New device is as sensitive as the best THz radiation detectors but it is a million times faster.

Tunnelling electrons make new type of transistor

Device consists of an ultrathin barrier of hexagonal boron nitride sandwiched between two graphene electrodes.

CdTe ink makes high-efficiency solar cell

Devices made using cadmium telluride layers have a sunlight-to-power conversion of efficiency of more than 10%.

Graphene drum could make good motion sensor and memory chip

Kavli researchers couple carbon resonator to a superconducting microwave cavity for the first time.

Watching nucleation from start to finish

Transmission electron microscopy obervations reveal the formation of the mineral calcium carbonate from start to finish.

2D-crystal jigsaw puzzle helps make high-quality heterojunction

Interface between two dichalcogenides could be used to fabricate transistors, LEDs and solar cells within a single atomically thin layer.

Ni-Co film has lots of active edges.

Device contact: more than just a phase

Manipulating the phase of MoS2 at contact points provides excellent low-resistance junctions for ultrathin transistors.

Ligands can make for patchy nanocrystal surface

Surprisingly, capping ligands only offer sparse covering say US researchers.

Nanotubular coating improves vascular stents

Nickel-titanium based medical implants are better when coated with tube-like structures.

Shedding more light on CNT photocurrent

Karlsruhe Institute of Nanotechnology work will help in the development of optoelectronics applications made from single-walled carbon nanotubes.

Strained WSe2 multilayers produce more light

California researchers see indirect-to-direct bandgap transition in tungsten selenide films.

Nanoindentation technique measures 2D elastic modulus

TMDCs and their heterostructures could be ideal for making flexible optoelectronics and photonics devices.
