By twisting layers of graphene, researchers discovered a unique electronic crystal where electrons freeze in place yet allow ...

To improve the durability of tin perovskite, a method called Ruddlesden-Popper (RP) has been proposed that introduces large ...

The direct band gap in tungsten diselenide allows for electrons to easily transition from the valence band to the conduction ...

Researchers have built a deep-ultraviolet microscope to study hard-to-analyze materials like diamond, offering a new way to probe their electronic and thermal properties at the nanoscale. This ...

Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap ...

with its 47 protons and electrons, and a lone electron in the outermost or "valence" shell. Yet silver (Ag) is more reactive than gold, and for reasons that took a long while to figure out.

There’s the pure mystery of how it happens: The phenomenon requires electrons, which carry electrical current, to pair up. Electrons repel each other, so how can they be united? Then there’s ...

Fusion energy has long been hailed as the “holy grail” of clean energy. However, the problem of runaway electrons has been a major hurdle in realizing the nuclear fusion process. The latest ...

Valence electrons with quantum properties are also expected to exhibit emergent phenomena, making these crystals essential for studying novel material functionalities. However, the extent to which ...

Using synchrotron infrared light and near-infrared/visible lasers without applying a magnetic field, we observed the response of valence electrons in the (C₂H₅)(CH₃)₃As[Pd(C₃S₅ ...
