Construction of a Seamless Graphene Spin Valve: Proximity Effects from van der Waals Magnet Cr₂Ge₂Te₆ Research Background and Significance Graphene, as a two-dimensional material, has significant potential applications in spintronics due to its excellent electron transport properties and long spin diffusion length. However, graphene’s intrinsic spi...

Background In recent years, researchers have shown significant interest in electron-hole crystals within Mott insulators. These types of crystals can achieve quantum excited states, have the potential to support counterflow superfluidity and topological order, and possess long-range quantum entanglement characteristics. However, experimental eviden...
