Concurrent phase retrieval for imaging strain in nanocrystals

Concurrent phase retrieval for imaging strain in nanocrystals
Concurrent phase retrieval for imaging strain in nanocrystals
Coherent diffraction imaging is a form of microscopy that permits high resolution imaging of atomic displacements from equilibrium where the use of conventional optics is not feasible. Approaches to date for the recovery of atomic displacements from equilibrium and subsequently strain information occur after phase reconstruction of the complex real-space images from at least three independent Bragg diffraction amplitude measurements. While this is a more accessible and effective approach to recover strain information, there is potential for erroneous results if the recovered phase information is not carefully treated. Here we present a strategy for imaging strain with coherent x-rays that eliminates the technical challenges that exist in conventional approaches by constructing the strain field concurrently during the phase retrieval process of recovering phase information.

Abstract

Coherent diffraction imaging is a form of microscopy that permits high resolution imaging of atomic displacements from equilibrium where the use of conventional optics is not feasible. Approaches to date for the recovery of atomic displacements from equilibrium and subsequently strain information occur after phase reconstruction of the complex real-space images from at least three independent Bragg diffraction amplitude measurements. While this is a more accessible and effective approach to recover strain information, there is potential for erroneous results if the recovered phase information is not carefully treated. Here we present a strategy for imaging strain with coherent x-rays that eliminates the technical challenges that exist in conventional approaches by constructing the strain field concurrently during the phase retrieval process of recovering phase information.
