Journal ArticleDOI
Photoelectron bremsstrahlung spectrum in synchrotron radiation excited total reflection x-ray fluorescence analysis of silicon wafers
TL;DR: In this paper, the background spectrum derived from the photoelectron bremsstrahlung is calculated using the Monte Carlo method using doubly differential electron cross sections obtained from the Born approximation modified by the Elwert factor.
Journal ArticleDOI
Design of an electron microscope phase plate using a focused continuous-wave laser
TL;DR: The relativistic quantum theory of the phase shift caused by the laser-electron interaction is presented, resonant cavities for enhancing the laser intensity are studied and applications in biology, soft-materials science and atomic and molecular physics are discussed.
Journal ArticleDOI
Plasmonic light trapping in nanostructured metal surfaces
TL;DR: In this paper, the plasmonic trapping of light in nanometer sized trenches etched into in a planar metal surface is shown to achieve complete absorption at any desired wavelength from the UV to the IR.
Journal ArticleDOI

TL;DR: An apparatus for measuring time-dependent x-ray diffraction is demonstrated, which measures the duration of 5-keV pulses from the Advanced Light Source synchrotron to be 70ps and in the averaging mode, trigger jitter results in 2-ps temporal resolution.
Journal ArticleDOI

TL;DR: In this article, an ensemble of nano-plates of lithium iron phosphate (LixFePO4) extracted from a battery electrode at 50% state of charge were used to quantify the electrochemical state and resolve phase boundaries throughout the volume of individual nano-particles.
