With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
Across the physical world, many intricate structures form via symmetry breaking. When a system with inherent symmetry transitions into an ordered state, it can form stable imperfections known as topological defects. Such ...
A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror device that may function as an optical transistor—with a switching speed around 10,000 times faster ...
Prof. Gal Shmuel of the Faculty of Mechanical Engineering at the Technion—Israel Institute of Technology has developed an innovative approach that enables precise control of heat conduction in ways that do not occur naturally.
Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...
Zoom in far enough on an empress cicada wing, and a strange landscape materializes. At the nanoscale, densely packed spires rise from the surface, covering the wing in an endless grove of bowling pins.
Researchers at Lawrence Livermore National Laboratory (LLNL) have optimized and 3D-printed helix structures as optical materials for terahertz (THz) frequencies, a potential way to address a technology gap for next-generation ...
A dissertation study at the University of Jyväskylä (Finland) developed two-dimensional fishnet-like structures from DNA origami for silicon surfaces and investigated how different conditions affect their formation. The results ...
Inspired by the Japanese art of kirigami, a team of scientists from the University of Amsterdam have developed a material that can reflect different colors of light, depending on how it is stretched. The results were recently ...
In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for creating entangled photon pairs, a critical component of emerging quantum technologies, using a crystalline ...
