An international team of scientists has developed a new way to produce single-layer graphene from a simple precursor: ethene - also known as ethylene - the smallest alkene molecule, which contains just two atoms of carbon.
Two-dimensional van der Waals heterostructures (2D vdW HSs) can be constructed by stacking different 2D materials together in nearly endless ways, and have significantly enriched the 2D materials family. They have attracted ...
Strange diamonds from an ancient dwarf planet in our solar system may have formed shortly after the dwarf planet collided with a large asteroid about 4.5 billion years ago, according to scientists.
Thin films play a key role in the production of electronics. They can be grown directly on a substrate surface through the chemical vapor deposition (CVD) process, which involves a reaction of vapor phase precursor compounds. ...
2-D materials have special lattice structures. Atoms in the same layer are usually bound by a covalent bond, while the force between layers is van der Waals coupling. They have super-clean surfaces without any dangling bonds. ...
The door to developing superior electronic devices, such as flexible circuits, has been nudged open by A*STAR researchers' modeling of possible methods to manufacture one of the crucial ingredients.
In a sense, says MIT chemical engineering professor Karen Gleason, you can trace the technology of chemical vapor deposition, or CVD, all the way back to prehistory: "When the cavemen lit a lamp and soot was deposited on ...
Researchers at Penn State's Center for Two-Dimensional and Layered Materials and the University of Texas at Dallas have shown the ability to grow high quality, single-layer materials one on top of the other using chemical ...
(Phys.org) —Atomically thin sheets of hexagonal boron nitride (h-BN) have the handy benefit of protecting what's underneath from oxidizing even at very high temperatures, Rice University researchers have discovered.
Mass production of large, uniform sheets of single-layer molybdenum disulfide, MoS2, is difficult, which limits its commercial application. A*STAR researchers have modified an existing manufacturing technique to enable the ...
