Abstract

Layered materials with buckled structure offer a promising route to explore distinct phases of quantum matter. Using GGA + DMFT we reveal the complex interplay between perpendicular electric field and site-diagonal disorder in the Dirac liquid electronic state of silicene. The electronic structure we derive is promising in the sense that it leads to results that might explain why out-of-plane electric field plus moderate disorder can generate marginal Dirac valleys consistent with scanning tunneling spectroscopy of silicene on Ag substrates.

狄拉克液体硅中电场与无序的相互作用

摘要

具有弯曲结构的层状材料为探索量子物质的不同相提供了一种有前途的途径。使用GGA + DMFT，我们揭示了Dirac液态电子硅状态下垂直电场与位点-对角线紊乱之间的复杂相互作用。我们得出的电子结构是有希望的，因为它导致的结果可能可以解释为什么平面外电场加中度无序可以产生与Ag衬底上的硅的扫描隧道光谱一致的边际Dirac谷。
