Role of temperature-dependent electron trapping dynamics in the optically driven nanodomain transformation in a PbTiO/SrTiO superlattice
Joonkyu Park, Youngjun Ahn, Jack A. Tilka +6
The spontaneously formed striped polarization nanodomain configuration of a PbTiO/SrTiO superlattice transforms to a uniform polarization state under above-bandgap illu…
Non-thermal fluence threshold for femtosecond pulsed x-ray radiation damage in perovskite complex oxide epitaxial heterostructures
Hyeon Jun Lee, Youngjun Ahn, Samuel D. Marks +13
Intense hard x-ray pulses from a free-electron laser induce irreversible structural damage in a perovskite oxide epitaxial heterostructure when pulse fluences exceed a threshold va…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
Dynamical slowing down in an ultrafast photo-induced phase transition
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +20
Complex systems, which consist of a large number of interacting constituents, often exhibit universal behavior near a phase transition. A slowdown of certain dynamical observables…
Nanosecond Optically Induced Phase Transformation in Compressively Strained BiFeO3 on LaAlO3
Youngjun Ahn, Anastasios Pateras, Samuel D. Marks +9
Above-bandgap optical illumination induces a transformation from tilted tetragonal-like (T-like) and rhombohedral-like (R-like) phases to an untilted T-like phase in compressively…
Anisotropic structural dynamics of monolayer crystals revealed by femtosecond surface x-ray scattering
I-Cheng Tung, Aravind Krishnamoorthy, Sridhar Sadasivam +22
X-ray scattering is one of the primary tools to determine crystallographic configuration with atomic accuracy. However, the measurement of ultrafast structural dynamics in monolaye…
