Skoltech researchers and their colleagues from the U.S. and Singapore have created a neural network that can help tweak semiconductor crystals in a controlled fashion to achieve superior properties for electronics. This enables a new direction of development of next-generation chips and solar cells by exploiting a controllable deformation that may change the properties of a material on the fly.
New mechanism of superconductivity discovered in graphene. Placing a 2D Bose-Einstein condensate in the vicinity of a graphene layer confers superconductivity to the material.
A team of scientists led by Nanyang Technological University, Singapore has found a way to process tamarind shells which are rich in carbon, converting the waste material into carbon nanosheets, which are a key component of supercapacitors - energy storage devices that are used in automobiles, buses, electric vehicles, trains, and elevators.
A new University of Wollongong study reviews progress on high-pressure studies on properties of iron-based superconductor (ISBC) families, and examines the use of pressure as a versatile method for exploring new materials.
The discovery of superconductivity in a second family of materials offers the opportunity to assess their similarities and differences and could bring us closer to understanding how high-temperature superconductivity arises.
A researcher from the University of Tsukuba has introduced a new theory for superconductivity that can better explain the results of recent experiments with high-temperature superconductors. By focusing on the "Berry connection," this work may lead to energy distribution with much less electrical resistance.
Using a new pressure quenching (PQ) technique at high temperatures to induce superconductivity in iron selenide (FeSe) crystals, superconductivity was achieved by Paul Chu and team at the Texas Center for Superconductivity at the University of Houston - and sustained without pressure.
Are new nickelate superconductors close kin to the original high-temperature superconductors, the cuprates? The first study of their magnetic properties says the answer is yes. Scientists from SLAC, Stanford and Diamond Light Source found important similarities but also subtle differences between the two.
"Heavy fermions" are an appealing theoretical way to produce quantum entangled phenomena, but until recently have been observed mostly in dangerously radioactive compounds. Researchers have now shown it is possible to make heavy fermions in subtly modified graphene, which is much cheaper and safer
Physicists used cross-correlation noise spectroscopy to measure miniscule fluctuations in electrical current flowing between materials inside silicon solar cells. The researchers identified crucial electrical noise signals that are completely invisible to conventional noise-measuring methods. They were also able to pinpoint the likely physical processes causing the noise, which often results in a loss of energy and lower efficiency. The technique is an important new tool to improve material interfaces for a better solar cell.
