“…Moving beyond traditional static characterization approaches toward in situ methods will allow us to capture the initial onset and evolution of local defects. In situ (scanning) transmission electron microscopy ((S)TEM) has been widely employed by the radiation effects community to examine defects in materials, − providing an invaluable window into irradiation-induced disorder, particularly in the low dose regime. These methods have long been used to examine bulk ceramics, ,− revealing radiation-induced defect formation pathways and kinetics.…”

Mastery of order–disorder processes in highly nonequilibrium nanostructured oxides has significant implications for the development of emerging energy technologies. However, we are presently limited in our ability to quantify and harness these processes at high spatial, chemical, and temporal resolution, particularly in extreme environments. Here, we describe the percolation of disorder at the model oxide interface LaMnO3/SrTiO3, which we visualize during in situ ion irradiation in the transmission electron microscope. We observe the formation of a network of disorder during the initial stages of ion irradiation and track the global progression of the system to full disorder. We couple these measurements with detailed structural and chemical probes, examining possible underlying defect mechanisms responsible for this unique percolative behavior.

“…In situ or operando techniques, where properties are monitored real time, provide a platform to characterize and understand the detailed evolution of materials in extreme environments. [51][52][53] Although advancements such as the combined irradiation and corrosion experiments are valuable, they still primarily rely upon postmortem characterization for quantifying materials evolution. In situ capabilities that directly observe these changes can provide a wealth of complementary information, particularly about kinetic properties.…”

Coupled extreme environments pose among the highest demands on materials, stressing the limits of temperature, pressure, electric and magnetic fields, atomic displacement rates, and chemical potentials that can be simultaneously sustained. This issue highlights exciting new materials science methods that will enable rapid progress in what has traditionally been the most difficult materials arena. New opportunities in artificial intelligence, multi-physics simulations capabilities, the use of extreme conditions to synthesize novel materials, and our ability to interrogate materials under relevant conditions provide new avenues to understand and design new materials.

“…Additionally, advanced analytical microscopy tools have been deployed recently on multibeam irradiation facilities to probe the chemistry and structure of materials through Electron Energy Loss Spectroscopy (EELS), Energy Filtered-TEM (EF-TEM), Scanning Transmission Electron Microscopy (STEM), Energy Dispersive x-ray Spectroscopy (EDXS) 64 and Automated Crystal Orientation Mapping (ACOM). 65 In addition to electrons, positrons are also used to investigate defect evolution within materials through positron annihilation spectroscopy (PAS or PALS). Capabilities for in situ positron doppler broadening for investigating defect evolution of bulk materials under irradiation have been developed.…”

The dynamic interactions of ions with matter drive a host of complex evolution mechanisms, requiring monitoring on short spatial and temporal scales to gain a full picture of a material response. Understanding the evolution of materials under ion irradiation and displacement damage is vital for many fields, including semiconductor processing, nuclear reactors, and space systems. Despite materials in service having a dynamic response to radiation damage, typical characterization is performed post-irradiation, washing out all information from transient processes. Characterizing active processes in situ during irradiation allows the mechanisms at play during the dynamic ion-material interaction process to be deciphered. In this review, we examine the in situ characterization techniques utilized for examining material structure, composition, and property evolution under ion irradiation. Covering analyses of microstructure, surface composition, and material properties, this work offers a perspective on the recent advances in methods for in situ monitoring of materials under ion irradiation, including a future outlook examining the role of complementary and combined characterization techniques in understanding dynamic materials evolution.
