You may not be able to hear it, but all solid materials make a sound. In fact, atoms—bound in lattices of chemical bonds—are never silent nor still: Under the placid surface of each and every object in our surroundings, a ...
A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit ...
It was a head-spinning discovery. In 2018, researchers in Japan claimed to find concrete evidence of an elusive particle, a Majorana fermion, in a quantum spin liquid called ruthenium trichloride. Majoranas are highly sought-after ...
Your phone warms up after a 20-minute FaceTime call. Your laptop hums loudly while editing a large video file. Heat is a by-product of modern electronics—from everyday gadgets to the high-resolution screens and processors ...
Control of heat transport in nanostructures is of central importance for numerous modern technologies—from high-performance computer chips that need to be cooled to energy converters—and is a highly active area of research. ...
Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications ...
Electronic nematicity is a phase of some crystalline solids in which electrons' collective properties, such as charge or spin densities, organize themselves into ordered patterns, lowering the crystal's rotational symmetry. ...
An international team of researchers, led by scientists from the University of California, Irvine, has demonstrated a fundamentally new way to make silicon emit light—overcoming one of the most persistent limitations in modern ...
Controlling heat flow is a major challenge for many technologies. In electronic and photonic devices, for example, heat dissipation can limit the performance and efficiency, as well as their potential for further miniaturization. ...
Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs.
