Two-dimensional Mechanical Metamaterials with Unusual Poisson Ratio Behavior
Zhibin Gao, Dan Liu, David Tomanek
We design two-dimensional (2D) mechanical metamaterials that may be deformed substantially at little or no energy cost. Examples of such deformable structures are assemblies of rig…
Is Twisted Bilayer Graphene Stable under Shear?
Xianqing Lin, Dan Liu, David Tománek
In twisted bilayer graphene (TBLG), extremely small deviations from the magic twist angle change its electronic structure near the Fermi level drastically,…
Microscopic Mechanism of the Helix-to-Layer Transformation in Elemental Group VI Solids
Dan Liu, Xianqing Lin, David Tomanek
We study the conversion of bulk Se and Te, consisting of intertwined a helices, to structurally very dissimilar, atomically thin two-dimensional (2D) layers of these elements. Our…
Towards room-temperature superconductivity in low-dimensional C60 nanoarrays: An ab initio study
Dogan Erbahar, Dan Liu, Savas Berber +1
We propose to raise the critical temperature for superconductivity in doped C molecular crystals by increasing the electronic density of states at the Fermi level $N(E…
