“…8 reproduce the main STS signals, showing overall metallic character and different power law behaviour near the neutrality point, albeit at sligtly different energies for the Dirac band minima. According to our results the top atoms feel stronger electric field effects, due to tip effects in STS [72], while the botton atoms are more prompt to disorder due to their proximity with Ag substrate. Importantly, our GGA + DMFT results capture the most salient features seen in experiment.…”

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.
