Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting ...
Quantum dots are semiconductor crystals only a few nanometers in size. Their ability to produce bright, precisely tunable colors has made them promising materials for light-emitting diodes, displays, solar cells and other ...
A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...
Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new experimental finding by researchers at Science Tokyo. Coupling these nanofibers with a ...
New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel ...
Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or ...
Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles lose their individual identities and behave as one collective object. For more than 60 years, researchers ...
Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, ...
Resolving a long-standing problem in semiconductor physics and optoelectronics, a team of researchers from Skoltech—a VEB.RF group institution—and their colleagues from ITMO University and HSE University have for the first ...
Electronic motion sets the stage for virtually every light-induced process in nature, from the first step of a chemical reaction to the flow of charge in a solid. Yet these processes unfold so rapidly that they can be observed ...
