Optically Induced Picosecond Lattice Compression in the Dielectric Component of a Strongly Coupled Ferroelectric/Dielectric Superlattice
Deepankar Sri Gyan, Hyeon Jun Lee, Youngjun Ahn +13
Above-bandgap femtosecond optical excitation of a ferroelectric/dielectric BaTiO3/CaTiO3 superlattice leads to structural responses that are a consequence of the screening of the s…
Structural evidence for ultrafast polarization rotation in ferroelectric/dielectric superlattice nanodomains
Hyeon Jun Lee, Youngjun Ahn, Samuel D. Marks +16
Weakly coupled ferroelectric/dielectric superlattice thin film heterostructures exhibit complex nanoscale polarization configurations that arise from a balance of competing electro…
Ultrafast carrier-lattice interactions and interlayer modulations of Bi2Se3 by X-ray free electron laser diffraction
Sungwon Kim, Youngsam Kim, Jaeseung Kim +20
As a 3D topological insulator, bismuth selenide (Bi2Se3) has potential applications for electrically and optically controllable magnetic and optoelectronic devices. How the carrier…
High-throughput ensemble characterization of individual core-shell nanoparticles with quantitative 3D density from XFEL single-particle imaging
Do Hyung Cho, Zhou Shen, Yungok Ihm +16
The structures, as building-blocks for designing functional nanomaterials, have fueled the development of versatile nanoprobes to understand local structures of noncrystalline spec…
Time-resolved resonant elastic soft X-ray scattering at Pohang Accelerator Laboratory X-ray Free Electron Laser
Hoyoung Jang, Hyeong-Do Kim, Minseok Kim +31
Resonant elastic X-ray scattering has been widely employed for exploring complex electronic ordering phenomena, like charge, spin, and orbital order, in particular in strongly corr…
