Dynamically suppressed lattice rotations in SrTiO as a basis for photo-induced ferroelectricity
Huaiyu Hugo Wang, Michael Fechner, Giovanni De Vecchi +22
Photo-induced ferroelectricity in the quantum paraelectric SrTiO involves the dynamical interplay between a coherently driven Ti-O stretching vibration and multiple structural…
Dynamic competition between phason and amplitudon observed by ultrafast multimodal scanning tunneling microscopy
Seokjin Bae, Arjun Raghavan, Soyeun Kim +7
The intertwining between two ordered states that arise from the same interactions is reflected in the dynamics of their coupled collective excitations. While the equilibrium phase…
In-situ and Non-contact Etch Depth Prediction in Plasma Etching via Machine Learning (ANN & BNN) and Digital Image Colorimetry
Minji Kang, Seongho Kim, Eunseo Go +10
Precise monitoring of etch depth and the thickness of insulating materials, such as Silicon dioxide and silicon nitride, is critical to ensuring device performance and yield in sem…
Revealing the hidden Dirac gap in a topological antiferromagnet using Floquet-Bloch manipulation
Nina Bielinski, Rajas Chari, Julian May-Mann +14
Manipulating solids using the time-periodic drive of a laser pulse is a promising route to generate new phases of matter. Whether such `Floquet-Bloch' manipulation can be achieved…
