Quantum simulation reveals mobility edge in a low-dimensional disordered landscape

Tue, 2018-08-21 20:50
Scientists using an innovative quantum simulation technique have made one of the first observations of a mobility edge in a low-dimensional system. Scientists were able to combine a disordered virtual material -- in this case a pair of coupled 1D chains -- with artificial magnetic fields to explore this phenomenon.

Link between magnetic field strength and temperature

Mon, 2018-08-20 21:00
Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process corresponds to the temperature of the material. Based on this finding, scientists can determine a sample's temperature to a resolution of one cubic micron by measuring the field strength at which this effect occurs. Temperature sensing is integral in most industrial, electronic and chemical processes, so greater spatial resolution could benefit commercial and scientific pursuits.

Mon, 2018-08-20 18:22
Scientists report they have successfully developed and tested the world's first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind. The flexible 2-D material-based device could someday restore sight to the millions of people with retinal diseases.

World's first-ever 4D printing for ceramics

Sat, 2018-08-18 21:28
A ground-breaking advancement in materials research by successfully developing the world's first-ever 4D printing for ceramics, which are mechanically robust and can have complex shapes. This could turn a new page in the structural application of ceramics.

A valley so low: Electrons congregate in ways that could be useful to 'valleytronics'

Sat, 2018-08-18 21:26
Researchers have made a finding that could help usher in new area of technology called 'valleytronics.' The study found that electrons in bismuth crystals prefer to collect in one valley rather than being distributed equally across valleys, setting up a type of electricity known as ferroelectricity.

Low bandwidth? Use more colors at once

Fri, 2018-08-17 04:02
As researchers engineer solutions for eventually replacing electronics with photonics, one team team has simplified the manufacturing process that allows utilizing multiple colors at the same time on an electronic chip instead of a single color at a time.

Twisted electronics open the door to tunable 2-D materials

Fri, 2018-08-17 00:02
Researchers report an advance that may revolutionize the field of 2-D materials such as graphene: a 'twistronic' device whose characteristics can be varied by simply varying the angle between two different 2-D layers placed on top of one another. The device provides unprecedented control over the angular orientation in twisted-layer devices, and enables researchers to study the effects of twist angle on electronic, optical, and mechanical properties in a single device.

Smallest transistor switches current with a single atom in solid electrolyte

Thu, 2018-08-16 19:49
Researchers have developed a single-atom transistor, the world's smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid state in a gel electrolyte. The single-atom transistor works at room temperature and consumes very little energy, which opens up entirely new perspectives for information technology.

Long-sought carbon structure joins graphene, fullerene family

Tue, 2018-08-14 04:31
Scientists have been playing with pure carbon compounds for centuries, starting with diamond and graphite and now with fullerenes, nanotubes and graphene. One type of 3D geometry has been missing, however: a negatively curved carbon-cage surface called schwarzite. Chemists have now shown that serendipitously produced materials called zeolite-templated carbons are in fact the long-sought schwarzites. Their recipe for making schwarzites could make them practical in electronics and gas storage.

Tying down electrons with nanoribbons

Wed, 2018-08-08 23:12
Nanoribbons are promising topological materials displaying novel electronic properties. Chemists and physicists have found a way to join two different types of nanoribbon to create a topological insulator that confines single electrons to the junction between them. Alternating nanoribbon types create a chain of interacting electrons that act as metals, insulators or interacting spins -- qubits for a quantum computer -- depending on separation. This opens the door to designer materials with unique quantum properties.
