Ultra-high-resolution imaging of moiré lattices and superstructures using scanning microwave impedance microscopy under ambient conditions
Kyunghoon Lee, M. Iqbal Bakti Utama, Salman Kahn +13
Two-dimensional heterostructures with layers of slightly different lattice vectors exhibit a new periodic structure known as moire lattices. Moire lattice formation provides a powe…

Visualization of the flat electronic band in twisted bilayer graphene near the magic angle twist
M. Iqbal Bakti Utama, Roland J. Koch, Kyunghoon Lee +15
Bilayer graphene was theorized to host a moire miniband with flat dispersion if the layers are stacked at specific twist angles known as the magic angles. Recently, such twisted bi…

Predicting Scattering Scanning Near-field Optical Microscopy of Mass-produced Plasmonic Devices
Lauren M. Otto, Stanley P. Burgos, Matteo Staffaroni +5
Scattering scanning near-field optical microscopy enables optical imaging and characterization of plasmonic devices with nanometer-scale resolution well below the diffraction limit…
