Based on first-principles calculations, we resent a method to reveal the elastic properties of recently synthesized monolayer hydrocarbon, graphane. The in-plane stiffness and Poisson’s ratio values are found to be smaller than those of graphene, and its yielding strain decreases in the presence of various vacancy defects and also at high ambient temperature. We also found that the band gap can be strongly modified by applied strain in the elastic range.

    We demonstrate the formation of well-ordered arrays of Mn nanoclusters of nearly identical sizes on a Si(111)-(7×7) surface. The Mn atoms are found not to react with the Si substrate at temperatures below ∼260 °C. At room temperature, the Mn clusters occupy both halves of the...
