Layer-Dependent Topological Phase in a Two-Dimensional Quasicrystal and Approximant
Jeffrey D. Cain, Amin Azizi, Matthias Conrad +2
Electronic and topological properties of materials are derived from the interplay between crystalline symmetry and dimensionality. Simultaneously introducing 'forbidden' symmetries…
Ultrafast spin-nematic and ferroelectric phase transitions induced by femto-second light pulses
Sangeeta Rajpurohit, Liang Z. Tan, Christian Jooss +1
Optically-induced phase transitions of the manganite have been simulated using a model Hamiltonian, that captures the dynamics of strongly correlated ch…
Phonon-Assisted Ballistic Current From First Principles Calculations
Zhenbang Dai, Aaron M. Schankler, Lingyuan Gao +2
The bulk photovoltaic effect (BPVE) refers to current generation due to illumination by light in a homogeneous bulk material lacking inversion symmetry. In addition to the intensiv…
Anisotropic band flattening in graphene with 1D superlattices
Yutao Li, Scott Dietrich, Carlos Forsythe +4
Patterning graphene with a spatially-periodic potential provides a powerful means to modify its electronic properties. Dramatic effects have been demonstrated in twisted bilayers w…
The Limits of Resolution and Dose for Aberration-Corrected Electron Tomography
Reed Yalisove, Suk Hyun Sung, Peter Ercius +1
Aberration-corrected electron microscopy can resolve the smallest atomic bond-lengths in nature. However, the high-convergence angles that enable spectacular resolution in 2D have…
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…
