Scientists uncover a process that stands in the way of making quantum dots brighter Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency. A new study explains why, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerat...

DOE Nanoscale Science Research Centers Support QIS Research to Advance Energy, Economic, and National Security DOE/US Department of Energy WASHINGTON, D.C. - The U.S. Department of Energy (DOE) today announced plans to provide $30 million for Quantum Information Science (QIS) research that helps scientists understand how nature works on an extremely small scale--100,000 times smaller than the diameter of a human hair. QIS can help our nation solve some of the most pressing and complex challenge...

Murugesans research--destined for Energy Sciences Center--adds to PNNLs battery technology contributions DOE/Pacific Northwest National Laboratory Vijayakumar "Vijay" Murugesan stands next to the X-ray photoelectron spectroscopy imaging system, which is attached to a glovebox via an in situ sample transfer port. The instrument helps Murugesan and other researchers design battery parts then conduct tests in the imaging system. The setup will move to the new Energy Sciences Center later this yea...

Lead Halide Perovskite may Lead to More Efficient Solar Cells Written by AZoMJan 22 2021 Among the group of materials called perovskites, one of the most fascinating is a material that is capable of changing solar light to electricity as efficiently as present-day silicon solar cells available in the market. This material could also be produced much more easily and cost-effectively. Scientists at SLAC National Accelerator Laboratory and Stanford University discovered that squeezing a promising ...

Credit: Tour Group/Rice University. Rice University scientists have extended their technique to produce graphene in a flash to tailor the properties of other 2D materials. The labs of chemist James Tour and materials theorist Boris Yakobson reported in the American Chemical Society’s ACS Nano they have successfully “flashed” bulk amounts of 2D dichalcogenides, changing them from semiconductors to metallics. Such materials are valuable for electronics, catalysis and as lubricants, among ot...
