2D room‐temperature magnetic materials are of great importance in future spintronic devices while only very few are reported. Herein, a plasma‐enhanced chemical vapor deposition approach is exploited to construct the 2D room‐temperature magnetic MnGa4‐H single crystal with a thickness down to 2.2 nm. The employment of H2 plasma makes hydrogen atoms can be easily inserted into the MnGa4 lattice to...
Ultralow thermal conductivity materials have triggered much interest due to diverse applications in thermal insulation, thermal barrier coating, and especially thermoelectrics. Two dimensional (2D) indium tellurides with ultralow thermal conductivity provide a versatile platform for tailoring the heat transfer, exploring new candidates for thermoelectrics, and achieving miniature, lightweight, and...
Optimizing the intrinsic activity of active sites is an appealing strategy for accelerating the kinetics of the catalytic process. Here, a design principle, namely “dual self‐built gating”, is proposed to tailor the electronic structures of catalysts. Catalytic improvement is confirmed in a model catalyst with a ReS2–WS2/WS2 hybridized heterostructure. As demonstrated in experimental and theoretical...
Germanium, the prime applied semiconductor, is widely used in solid‐state electronics and photoelectronics. Unfortunately, since the 3D diamond‐like structure with strong covalent bonds impedes the 2D anisotropic growth, only the examples of ultrathin Ge along the (111) plane have been investigated, much less to the controllable synthesis along another crystal surface. Meanwhile, Ge(111) flakes are...
