      Engineering Three-Dimensional Moire Flat Bands 

      Xian, Lede; Fischer, Ammon; Claassen, Martin; Zhang, Jin; Rubio Secades, Angel; Kennes, Dante M. (American Chemical Society, 2021-09-22)
      Twisting two adjacent layers of van der Waals materials with respect to each other can lead to flat two-dimensional electronic bands which enables a wealth of physical phenomena. Here, we generalize this concept of so-called ...

      Germanene: a novel two-dimensional germanium allotrope akin to graphene and silicene 

      Dávila, M. E.; Xian, Lede; Cahangirov, S.; Rubio Secades, Angel; Le Lay, G. (IOP Publishing, 2014-09-09)
      We have grown an atom-thin, ordered, two-dimensional multi-phase film in situ through germanium molecular beam epitaxy using a gold (111) surface as a substrate. Its growth is similar to the formation of silicene layers ...

      Moireless Correlations in ABCA Graphene 

      Kerelsky, Alexander; Rubio Verdú, Carmen; Xian, Lede; Kennes, Dante M.; Halbertal, Dorri; Finney, Nathan; Song, Larry; Turkel, Simon; Wang, Lei; Watanabe, Kenji; Taniguchi, Takashi; Hone, James; Dean, Cory R.; Basov, Dmitri N.; Rubio Secades, Angel; Pasupathy, Abhay N. (National Academy of Sciences, 2021-01-26)
      Atomically thin van der Waals materials stacked with an interlayer twist have proven to be an excellent platform toward achieving gate-tunable correlated phenomena linked to the formation of flat electronic bands. In this ...

      One-dimensional flat bands in twisted bilayer germanium selenide 

      Kennes, Dante M.; Xian, Lede; Claassen, Martin; Rubio Secades, Angel (Nature Publishing, 2020-02-28)
      Experimental advances in the fabrication and characterization of few-layer materials stacked at a relative twist of small angle have recently shown the emergence of flat energy bands. As a consequence electron interactions ...

      Realization of nearly dispersionless bands with strong orbital anisotropy from destructive interference in twisted bilayer MoS2 

      Xian, Lede; Claassen, Martin; Kiese, Dominik; Scherer, Michael M.; Trebst, Simon; Kennes, Dante M.; Rubio Secades, Angel (Nature Research, 2021-09)
      [EN]Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructures in a controlled manner, giving rise ...
