THz-induced phonon mode mixing and collective dynamics in a polar nanolattice
Elizabeth Skoropata, Peter M. Derlet, Hiroki Ueda +13
Manipulating phonons through symmetry is a fundamental approach to alter the dynamic responses of materials. Most often new phases are sought through control of the unit-cell (e.g.…
Contrastive Image-Metadata Pre-Training for Materials Transmission Electron Microscopy
Georgia Channing, Debora Keller, Marta D. Rossell +3
The transmission electron microscope facilitates the highest-resolution imaging of any instrument ever created, and its limiting factor is no longer spatial resolution but dose eff…
Control of polarization and polar chiral textures in BiFeO by epitaxial strain and interfacial chemistry
Elzbieta Gradauskaite, Natascha Gray, Quintin N. Meier +2
The balance between interfacial chemistry, electrostatics, and epitaxial strain plays a crucial role in stabilizing polarization in ferroelectric thin films. Here, we bring these c…
Nanoscale electrostatic control in ferroelectric thin films through lattice chemistry
Ipek Efe, Alexander Vogel, William S. Huxter +7
Nanoscale electrostatic control of oxide interfaces enables physical phenomena and exotic functionalities beyond the realm of the bulk material. In technologically-relevant ferroel…
Magnetostructural Coupling at the Néel point in YNiO3 Single Crystals

Recently a highly ordered Moiré dislocation lattice was identified at the interface between a \ce{SrTiO3} (STO) thin film and the (LaAlO)(SrTaAlO) (LSAT…
Defeating depolarizing fields with artificial flux closure in ultrathin ferroelectrics
Elzbieta Gradauskaite, Quintin N. Meier, Natascha Gray +6
Material surfaces encompass structural and chemical discontinuities that often lead to the loss of the property of interest in the so-called dead layers. It is notably problematic…
Time-dependent multistate switching of topological antiferromagnetic order in MnSn
