θ-Tunable Photoluminescence from Interlayer Excitons in Twisted Bilayer Graphene
Hiral Patel, Lujie Huang, Cheol-Joo Kim +2
Using resonant 2-photon excitation of interlayer electrons in twisted bilayer graphene (tBLG), we resolve photoluminescence (PL) that tunes spectrally with stacking angle, θ. This…

Strain Mapping of Two-Dimensional Heterostructures with Sub-Picometer Precision
Yimo Han, Kayla Nguyen, Michael Cao +7
Next-generation, atomically thin devices require in-plane, one-dimensional heterojunctions to electrically connect different two-dimensional (2D) materials. However, the lattice mi…

Deep sub-Ångstrom imaging of 2D materials with a high dynamic range detector
Yi Jiang, Zhen Chen, Yimo Han +9
Aberration-corrected optics have made electron microscopy at atomic-resolution a widespread and often essential tool for nanocharacterization. Image resolution is dominated by beam…
