Laser pulses light the way to tuning topological materials for spintronics and quantum computing
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a means of controlling the surface conductivity of a three-dimensional (3-D) topological insulator, a type of material that has potential applications ...
Scientists image conducting edges in a promising 2-D material
A research team comprised of scientists at the University of California, Riverside, and the University of Washington has for the first time directly imaged "edge conduction" in monolayer tungsten ditelluride, or WTe2, a newly ...
Understanding insulators with conducting edges
Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled ...
Scientists realize a three-dimensional 'topological' medium for electromagnetic waves
Topological insulators are exotic states of matter that physicists have been intensely studying for the past decade. Their most intriguing feature is that they can be rigorously distinguished from all other materials using ...
Researchers discover a metamaterial with inherently robust sound transport
Researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York and at the City College of New York (CCNY) have developed a metamaterial that can transport sound in unusually ...
'Magnetic topological insulator' makes its own magnetic field
A team of U.S. and Korean physicists has found the first evidence of a two-dimensional material that can become a magnetic topological insulator even when it is not placed in a magnetic field.
First two-dimensional material that performs as both topological insulator and superconductor
A transistor based on the 2-D material tungsten ditelluride (WTe2) sandwiched between boron nitride can switch between two different electronic states—one that conducts current only along its edges, making it a topological ...
Exploring new spintronics device functionalities in graphene heterostructures
Graphene Flagship researchers have shown in a paper published in Science Advances how heterostructures built from graphene and topological insulators have strong, proximity induced spin-orbit coupling which can form the basis ...
A novel topological insulator
For the first time, physicists have built a unique topological insulator in which optical and electronic excitations hybridize and flow together. They report their discovery in Nature.
