Hidden dormant phase mediating the glass transition in disordered matter
Eunyoung Park, Sinwoo Kim, Melody M. Wang +14
Metallic glass is a frozen liquid with structural disorder that retains degenerate free energy without spontaneous symmetry breaking to become a solid. For over half a century, thi…
Photoinduced surface plasmon control of ultrafast melting modes in Au nanorods
Eunyoung Park, Chulho Jung, Junha Hwang +11
Photoinduced ultrafast phenomena in materials exhibiting nonequilibrium behavior can lead to the emergence of exotic phases beyond the limits of thermodynamics, presenting opportun…
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…
