With the highest possible spatial resolution of less than a millionth of a millimetre, electron microscopes make it possible to study the properties of materials at the atomic level and thus demonstrate the realm of quantum mechanics.
Photonic integrated circuits that use light instead of electricity for computing and signal processing promise greater speed, increased bandwidth, and greater energy efficiency than traditional circuits using electricity.
Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have created next-generation solar modules with high efficiency and good stability. Made using a type of material called perovskites, these solar modules can maintain a high performance for over 2000 hours.
Munich geophysicists have measured Earth’s spin and axis orientation with a novel ring laser, and provided the most precise determination of these parameters yet achieved by a ground-based instrument without the need for stellar range finding.
In combined theoretical and experimental work, ETH physicists introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The discovery opens up a route to engineering quantum-optical phenomena in a variety of materials and devices.
Researchers at Columbia Engineering and Montana State University report today that they have found that placing sufficient strain in a 2D material—tungsten diselenide (WSe2)—creates localized states that can yield single-photon emitters.
