    Boron Triangular Kagome Lattice with Half-Metallic Ferromagnetism

    Based on the first-principles evolutionary materials design, we report a stable boron Kagome lattice composed of triangles in triangles on a two-dimensional sheet. The Kagome lattice can be synthesized on a si...

    Universal Conductance Fluctuation in Two-Dimensional Topological Insulators

    Despite considerable interest in two-dimensional (2D) topological insulators (TIs), a fundamental question still remains open how mesoscopic conductance fluctuations in 2D TIs are affected by spin-orbit intera...
