Charge-polarized interfacial superlattices in marginally twisted hexagonal boron nitride
C. R. Woods, P. Ares, H. Nevison-Andrews +7
When two-dimensional crystals are brought into close proximity, their interaction results in strong reconstruction of electronic spectrum and local crystal structure. Such reconstr…
Holographic reconstruction of the interlayer distance of bilayer two-dimensional crystal samples from their convergent beam electron diffraction patterns
Tatiana Latychevskaia, Yichao Zou, Colin Robert Woods +5
The convergent beam electron diffraction (CBED) patterns of twisted bilayer samples exhibit interference patterns in their CBED spots. Such interference patterns can be treated as…
Convergent beam electron diffraction of multilayer van der Waals structures
Tatiana Latychevskaia, Colin Robert Woods, Yi Bo Wang +4
Convergent beam electron diffraction is routinely applied for studying deformation and local strain in thick crystals by matching the crystal structure to the observed intensity di…
Nonlinear optical study of commensurability effects in graphene-hBN heterostructures
E. A. Stepanov, S. V. Semin, C. R. Woods +4
Second-order nonlinear optical response allows to detect different properties of the system associated with the inversion symmetry breaking. Here, we use a second harmonic generati…
