- Assessing the impact of loss mechanisms in solar cell candidate antimony sulfide selenide 19/05/2022 As climate change continues to present itself as the most pressing threat facing our planet, researchers push to find efficient and clean alternatives to fossil fuels. Foremost among this research is harnessing free energy from the sun. Doing this efficiently requires advanced knowledge of the qualities of materials used in the construction of solar cells.
- Non-invasive imaging of atomic arrangement at the sub-angstrom scale in 2-D hybrid perovskites 17/05/2022 Materials scientists aim to identify the atomic arrangement of 2D Ruddlesden-Popper hybrid perovskites (RPP) using non-invasive imaging; however, the process is challenging due to the insulating nature and softness of the organic layers.
- From conventional to strange metal behavior in magic-angle twisted bilayer graphene 12/05/2022 Magic-angle twisted bilayer graphene (MATBG) is a graphene-based material with a unique structure, consisting of two graphene sheets layered on top of each other with a misalignment of approximately 1.1°. This unique structure has been found to host various interesting states, including correlated insulating states and unconventional superconductivity.
- Beyond van der Waals: The next generation of covalent 2D-2D heterostructures 10/05/2022 A team of scientists have "velcroed" 2D structures of MoS2 and graphene using a covalent connection for the first time. The 2D-2D structures were used to build robust field effect transistors with controlled electronic communication, interface chemical nature and interlayer distance.
- Skyrmions on the rise: New 2D material advances low-power computing 05/05/2022 Two-dimensional magnetic materials have been hailed as building blocks for the next generation of small, fast electronic devices. These materials, made of layers of crystalline sheets just a few atoms thick, gain their unique magnetic properties from the intrinsic compass-needle-like spins of their electrons. The sheets' atomic-scale thinness means that these spins can be manipulated on the finest scales using external electric fields, potentially leading to novel low-energy data storage and information processing systems. But knowing exactly how to design 2D materials with specific magnetic properties that can be precisely manipulated remains a barrier to their application.
- Lasers trigger magnetism in atomically thin quantum materials 03/05/2022 Researchers have discovered that light—in the form of a laser—can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons. These subatomic particles have an electronic property called "spin," which has a potential application in quantum computing. The researchers found that electrons within the material became oriented in the same direction when illuminated by photons from a laser.
