Ultrathin solar cells get a boost from 2D perovskite

Nov 22, 2021 (Nanowerk News) Rice University engineers have achieved a new benchmark in the design of atomically thin solar cells made of semiconducting perovskites, boosting their efficiency while retaining their ability to stand up to the environment. The lab of Aditya Mohite of Rice’s George R. Brown School of...

Getting quantum dots to stop blinking

Nov 22, 2021 (Nanowerk News) Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions. But for some potential uses, such as tracking biochemical pathways of a drug as it interacts with living cells, progress...

Mystery of high performing novel solar cell materials revealed in stunning clarity

Nov 22, 2021 (Nanowerk News) Researchers from the University of Cambridge have used a suite of correlative, multimodal microscopy methods to visualise, for the first time, why perovskite materials are seemingly so tolerant of defects in their structure. Their findings were published in Nature Nanotechnology ("Nanoscale chemical heterogeneity dominates the...

Spin mixing in ferromagnets revealed

Nov 22, 2021 (Nanowerk News) For the first time through experiments and theory, Uppsala researchers, together with international collaborators, have been able to measure spin mixing in a ferromagnetic material (Physical Review Letters, "Quantifying Spin-Mixed States in Ferromagnets"). Through the experimental measurements, they discovered that a common factor in spin...

Scientists discover the first ferromagnetic quasicrystals

Nov 22, 2021 (Nanowerk News) Long-range magnetic order has been observed in quasicrystals, strange solids that show forbidden crystal symmetries, for the first time. Since the discovery of quasicrystals (QCs), solids that mimic crystals in their long-range order but lack periodicity, scientists have sought physical properties related to their peculiar...
