Local interface effects modulate global charge order and optical properties of 1T-TaS/1H-WSe heterostructures
Samra Husremović, Valerie S. McGraw, Medha Dandu +14
1T-TaS is a layered charge density wave (CDW) crystal exhibiting sharp phase transitions and associated resistance changes. These resistance steps could be exploited for inform…
Mic-hackathon 2024: Hackathon on Machine Learning for Electron and Scanning Probe Microscopy
Utkarsh Pratiush, Austin Houston, Kamyar Barakati +70
Microscopy is a primary source of information on materials structure and functionality at nanometer and atomic scales. The data generated is often well-structured, enriched with me…
Considerations for extracting moiré-level strain from dark field intensities in transmission electron microscopy
Isaac M. Craig, Madeline Van Winkle, Colin Ophus +1
Bragg interferometry (BI) is an imaging technique based on four-dimensional scanning electron microscopy (4D-STEM) wherein the intensities of select overlapping Bragg disks are fit…
Atomic engineering of interfacial polarization switching in van der Waals multilayers
Madeline Van Winkle, Nikita Dowlatshahi, Nikta Khaloo +6
In conventional ferroelectric materials, polarization is an intrinsic property limited by bulk crystallographic structure and symmetry. Recently, it has been demonstrated that pola…
Local atomic stacking and symmetry in twisted graphene trilayers
Isaac M. Craig, Madeline Van Winkle, Catherine Groschner +7
Moiré superlattices formed from twisting trilayers of graphene are an ideal model for studying electronic correlation, and offer several advantages over bilayer analogues, includin…
Rotational and Dilational Reconstruction in Transition Metal Dichalcogenide Moiré Bilayers
Madeline Van Winkle, Isaac M. Craig, Stephen Carr +9
Lattice reconstruction and corresponding strain accumulation play a key role in defining the electronic structure of two-dimensional moiré superlattices, including those of transit…
Hard ferromagnetism down to the thinnest limit of iron-intercalated tantalum disulfide
Samra Husremović, Katherine Inzani, Catherine K. Groschner +11
Two-dimensional (2D) magnetic crystals hold promise for miniaturized and ultralow power electronic devices that exploit spin manipulation. In these materials, large, controllable m…
Tunable electrochemistry with moiré flat bands and topological defects at twisted bilayer graphene
Yun Yu, Kaidi Zhang, Holden Parks +9
Tailoring electron transfer dynamics across solid-liquid interfaces is fundamental to the interconversion of electrical and chemical energy. Stacking atomically thin layers with a…
Strain fields in twisted bilayer graphene
Nathanael P. Kazmierczak, Madeline Van Winkle, Colin Ophus +7
Van der Waals heteroepitaxy allows deterministic control over lattice mismatch or azimuthal orientation between atomic layers to produce long wavelength superlattices. The resultin…
