Dynamical diffraction formalism for imaging time-dependent diffuse scattering from coherent phonons with Dark-Field X-ray Microscopy
Darshan Chalise, Brinthan Kanesalingam, Dorian P. Luccioni +3
Coherent acoustic phonons, whose damping sets the upper bound of quality factors in acoustic resonators, play a critical role in advanced telecommunication and quantum information…
Computation and Sensitivity Analysis of the Deformation-Gradient Tensor Reconstruction in Dark-Field X-ray Microscopy
Brinthan Kanesalingam, Darshan Chalise, Carsten Detlefs +1
Spatially resolved strain measurements are crucial to understanding the properties of engineering materials. Although strain measurements utilizing techniques such as transmission…
Oblique diffraction geometry for the observation of several non-coplanar Bragg reflections under identical illumination
C. Detlefs, A. Henningsson, B. Kanesalingam +9
We present a method to determine the strain tensor and local lattice rotation with Dark Field X-ray Microscopy. Using a set of at least 3 non-coplanar, symmetry-equivalent Bragg re…
Planar 3 and 2 Method for Increased Sensitivity to Through-Plane Thermal Properties
Darshan Chalise, Brinthan Kanesalingam, Divya Chalise
Accurately measuring the thermal properties of buried interfaces is crucial for understanding heat transport in multilayered materials, particularly in applications such as batteri…
