An international team of scientists, including NUST MISIS's Professor Gotthard Seifert, have made an important step towards the control of excitonic effects in two-dimensional van der Waals heterostructures. In the future, this research will help to create electronics with more controlled properties. The research has been published in Nature Physics.
The first ever detailed pictures of the structure of conjugated polymers have been produced by a research team led by Professor Giovanni Costantini at the University of Warwick.
In Neuchâtel, Switzerland, researchers from EPFL and CSEM have combined silicon- and perovskite-based solar cells. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent.
Quantum bits are now easier to manipulate for devices in quantum computing, thanks to enhanced spin-orbit interaction in silicon.
A laser pulse that for a few picoseconds transforms a material into a high-temperature superconductor. Different experiments have unveiled this interesting phenomenon, with potential applicative implications. Research carried out by SISSA scientists a year ago had already provided several basic principles of the phenomenon. A new study published on "Physical Review Letters" now clarifies other important aspects.
The new material is needful to develop instruments for the high-precise measuring of distances, terrestrial and space optical communications, pollution monitoring, implementation of new modes of laser processing, information recording and storage.
Researchers have synthesized the first molecule capable of insulating at the nanometer scale more effectively than a vacuum barrier. The team's insight was to exploit the wave nature of electrons. By designing an extremely rigid silicon-based molecule under 1 nm in length that exhibited comprehensive destructive interference signatures, they devised a novel technique for blocking tunnelling conduction. This new design principle has the potential to support continued miniaturization of classic transistors in the near term.
Researchers at Oregon State University are looking at a highly durable organic pigment, used by humans in artwork for hundreds of years, as a promising possibility as a semiconductor material.
A research team led by Jigang Wang of Iowa State University and the Ames Laboratory has developed a new quantum switching scheme that gives them access to new and hidden states of matter. If researchers can learn to control the hidden state, further stabilize it and determine whether it's suitable for quantum logic operations, it could allow researchers to use it for quantum computing and other practical functions. The journal Nature Materials has just published a paper about the discovery.
Researchers at MIT and Technion have devised a new way to make light interact with matter. Reducing the wavelength of light could allow it to be absorbed or emitted by a semiconductor, their study suggests.
