The discovery of the material graphene, which consists of only one layer of carbon atoms, was the starting signal for a global race: Today, so-called "2D materials" are produced, made of different types of atoms. Atomically thin layers that often have very special material properties not found in conventional, thicker materials.
Metal-insulator transition (MIT) driven by many-body interactions is an important phenomenon in condensed matter physics. Exotic phases always emerge around the metal-insulator transition points where quantum fluctuations arise from a competition among spin, charge, orbital, and lattice degrees of freedom.
Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs.
The recent synthesis of one-dimensional van der Waals heterostructures, a type of heterostructure made by layering two-dimensional materials that are one atom thick, may lead to new, miniaturized electronics that are currently not possible, according to a team of Penn State and University of Tokyo researchers.
In recent years, engineers have found ways to modify the properties of some "two- dimensional" materials, which are just one or a few atoms thick, by stacking two layers together and rotating one slightly in relation to the other. This creates what are known as moiré patterns, where tiny shifts in the alignment of atoms between the two sheets create larger-scale patterns. It also changes the way electrons move through the material, in potentially useful ways.
Current electronic components in computers, mobile phones and many other devices are based on microstructured silicon carriers. However, this technology has almost reached its physical limits and the smallest possible structure sizes.
Experienced silicone product manufacturer General Silicones (GS) shares how its Compo-SiL® technology is a new alternative to heat transfer printing or silicone-based ink printing. Bulk Fabric Printing and Wholesale companies see an increased demand for silicone logo prints due to silicone material’s eco-friendly properties. With consumer scrutiny focusing on green product specifications, apparel and sports brands need an eco-friendly solution. Using silicone ink for printing is an approach often used. But so far, silicone ink printing technology does not allow for shades and complicated patterns and requires time and labor-intensive processes.
Semiconducting 2D alloys could be key to overcoming the technical limitations of modern electronics. Although 2D Si-Ge alloys would have interesting properties for this purpose, they were only predicted theoretically. Now, scientists from Japan Advanced Institute of Science and Technology have realized the first experimental demonstration. They have also shown that the Si to Ge ratio can be adjusted to fine tune the electronic properties of the alloys, paving the way for novel applications.
LMI Technologies (LMI), a leading developer of 3D scanning and inspection solutions, is pleased to announce the official launch of Gocator® 6.1 software. This release includes the groundbreaking addition of high accuracy 6DoF alignment and 3D mesh data generation for advanced shape measurement on 360º surface scans (using multi-sensor systems); a new 2D contour-based part and feature locator with Surface Pattern Matching; a GoHMI SDK toolkit for developing Gocator®-to-factory operator interfaces; and a number of other smart 3D technology capabilities that drive improved automated quality inspection in the context of IIoT and industry 4.0.
Physicists at Washington University in St. Louis have discovered how to locally add electrical charge to an atomically thin graphene device by layering flakes of another thin material, alpha-RuCl3, on top of it.
