Wafer Scale Hexagonal Boron Nitride Films Have Been Created

Dongguk University and other Korean researchers have made wafer scale hexagonal boron nitride films with a nearly perfect single-crystalline structure. The film self-assembles on top of liquid gold. Hexagonal boron nitride (hBN) is also called white graphite. They can be single atom thick crystalline films. They have an insulating effect that has found uses in …

Fabrication of Ultrastrong 700 Gigapascal Fused Double-walled Carbon Nanotubes

The Clean Energy Research Foundation has discovered a method of manufacturing the worlds strongest and toughest materials. Fused double-walled carbon nanotube (DWNT) fibers were made with a strength of a 700 GPa Young’s modulus. This strength was seen in prior experiments, in 2010 and 2011, where electron beams welded DWNTs in microscopic bundles together and …

3D Atomic Quantum Chips and Advance to Eventual Large Scale Quantum Tech

Australia’s New South Wales scientists have adapted single atom technology to build 3D silicon quantum chips – with precise interlayer alignment and highly accurate measurement of spin states. The 3D architecture is considered a major step in the development of a blueprint to build a large-scale quantum computer. They aligned the different layers in their …

Atom thin magnetic memory

Researchers report that they used stacks of ultrathin materials to exert unprecedented control over the flow of electrons based on the direction of their spins — where the electron “spins” are analogous to tiny, subatomic magnets. The materials that they used include sheets of chromium tri-iodide (CrI3), a material described in 2017 as the first …

Solving the issues around connecting nanowires to single atom qubits

NIST researchers have pioneered a process that drastically simplifies fabrication of the kind of nanoscale microchip features that may soon form the basis of a quantum computer, among other applications. Instead of conventional 1-or-0 computer bits stored in the form of electrical charges, quantum information is stored and manipulated in the form of quantum bits …

Atomic lattice crystal seamlessly sewn together to make atomically thin fabrics

Scientists with the University of Chicago and Cornell University revealed a technique to “sew” two patches of crystals seamlessly together at the atomic level to create atomically-thin fabrics. The team wanted to do this by stitching different fabric-like, three-atom-thick crystals. “Usually these are grown in stages under very different conditions; grow one material first, stop …
