Imaging Electron-Hole Asymmetry in the Quantum Melting of Generalized Wigner Crystals
Emma Berger, Michael Arumainayagam, Zhihuan Dong +12
Two-dimensional moiré materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy (STM) we have imaged t…
Visualizing the Impact of Quenched Disorder on 2D Electron Wigner Solids
Zhehao Ge, Conor Smith, Zehao He +17
Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem…
Atomic dynamics and local structural disorder during ultrafast melting of polycrystalline Pd
Adam Olczak, Ryszard Sobierajski, Przemyslaw Dziegielewski +8
The primary distinction between solid and liquid phases is mechanical rigidity, with liquids having a disordered atomic structure that allows flow. While melting is a common phase…
Low Resistance Ohmic Contact to P-type Monolayer WSe2
Jingxu Xie, Zuocheng Zhang, Haodong Zhang +13
Advanced microelectronics in the future may require semiconducting channel materials beyond silicon. Two-dimensional (2D) semiconductors, characterized by their atomically thin thi…
Three-dimensional imaging of buried heterointerfaces
Colum M. O'Leary, Haozhi Sha, Jianhua Zhang +6
We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We i…
Visualizing and manipulating chiral interface states in a moiré quantum anomalous Hall insulator
Canxun Zhang, Tiancong Zhu, Salman Kahn +7
Moiré systems made from stacked two-dimensional materials host novel correlated and topological states that can be electrically controlled via applied gate voltages. We have used t…
