Non-contact, non-destructive mapping of thermal diffusivity and surface acoustic wave speed using transient grating spectroscopy
Abdallah Reza, Cody A. Dennett, Michael P. Short +5
We present new developments of the laser-induced transient grating spectroscopy (TGS) technique that enable the measurement of large area 2D maps of thermal diffusivity and surface…

Glancing-Incidence Focussed Ion Beam Milling: A Coherent X-ray Diffraction Study of 3D Nano-scale Lattice Strains and Crystal Defects
Felix Hofmann, Ross J. Harder, Wenjun Liu +3
This study presents a detailed examination of the lattice distortions introduced by glancing incidence Focussed Ion Beam (FIB) milling. Using non-destructive multi-reflection Bragg…
