Correlated electronic phases in twisted bilayer transition metal dichalcogenides
Lei Wang,Lei Wang,En-Min Shih,Augusto Ghiotto,Lede Xian,Daniel Rhodes,Cheng Tan,Martin Claassen,Dante M. Kennes,Dante M. Kennes,Yusong Bai,Bumho Kim,Kenji Watanabe,Takashi Taniguchi,Xiaoyang Zhu,James Hone,Angel Rubio,Angel Rubio,Abhay Pasupathy,Cory Dean +19 more
TL;DR: The observation of tunable collective phases in a simple band, which hosts only two holes per unit cell at full filling, establishes twisted bilayer transition metal dichalcogenides as an ideal platform to study correlated physics in two dimensions on a triangular lattice.
Journal ArticleDOI
Magic continuum in twisted bilayer WSe2
Lei Wang,En-Min Shih,Augusto Ghiotto,Lede Xian,Daniel Rhodes,Cheng Tan,Martin Claassen,Dante M. Kennes,Yusong Bai,Bumho Kim,Kenji Watanabe,Takashi Taniguchi,Xiaoyang Zhu,James Hone,Angel Rubio,Abhay Pasupathy,Cory Dean +16 more
TL;DR: In this article, twisted bilayer tungsten diselenide (tWSe2), a semiconducting transition metal dichalcogenide (TMD), the authors observed correlated states over a continuum of angles, spanning 4 degree to 5.1 degree.

TL;DR: A simple, room-temperature, ambient method to visualize real-space moiré superlattices with sub-5-nm spatial resolution in a variety of twisted van der Waals heterostructures including, but not limited to, conducting graphene, insulating boron nitride and semiconducting transition metal dichalcogenides is described.
