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…
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…
An x-ray probe of laser-aligned molecules
Emily R. Peterson, Christian Buth, Dohn A. Arms +8
We demonstrate a hard x-ray probe of laser-aligned small molecules. To align small molecules with optical lasers, high intensities at nonresonant wavelengths are necessary. We use…
Transient x-ray absorption spectroscopy of hydrated halogen atom
Christopher G. Elles, Ilya A. Shkrob, Robert A. Crowell +2
Time-resolved x-ray absorption spectroscopy monitors the transient species generated by one-photon detachment of an electron from aqueous bromide. Hydrated bromine atoms with a lif…
Development of an X-band Photoinjector at SLAC
A. E. Vlieks, G. Caryotakis, R. Loewen +6
As part of a National Cancer Institute contract to develop a compact source of monoenergetic X-rays via Compton backscattering, we have completed the design and construction of a 5…
