Moiré superlattices are periodic patterns formed when two or more thin semiconducting layers are stacked with a small twist angle or lattice mismatch. When 2D materials form these patterns, their electronic, mechanical, and ...
In the nanometer range (billionth of a meter), interactions occur between light and matter that do not happen on larger scales. As such, so-called nanophotonic materials have unique optical properties that open up a whole ...
A moiré pattern appears when you stack and rotate two copies of an image with regularly repeating shapes, turning simple patterns of squares or triangles into a groovy wave pattern that moves across the combined image in ...
Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by excited particles, due to photons of the same frequency triggering further emissions. This phenomenon ...
Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In quantum technology applications ...
Electrons typically travel at high speeds, zipping through matter unbound. In the 1930s, physicist Eugene Wigner predicted that electrons could be coaxed into stillness at low densities and cold temperatures, forming an electron ...
A U.S. Naval Research Laboratory (NRL) multi-disciplinary team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic information on a single photon ...
In 2018, a discovery in materials science sent shock waves throughout the community. A team showed that stacking two layers of graphene—a honeycomb-like layer of carbon extracted from graphite—at a precise "magic angle" turned ...
The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the atomic level manufacturing of semiconductors. The basic idea of atomic level manufacturing ...
Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, ...
