Dislocations are ubiquitous linear defects and are responsible for many of the properties of
crystalline materials. Studies on the glide process of dislocations in bulk materials have …

The migration of point defects, for example, crystal lattice vacancies and self-interstitial
atoms (SIAs), typically occurs through three-dimensional random walk in crystalline solids …

A study on zirconium nitride was performed to assess the effect of radiation damage by
heavy ions at cryogenic and elevated temperatures. Cross-sectional transmission electron …

Crystal surface bombardment by atoms or molecules, neutral or ionized, occurs both in
ambient conditions and in many technological operations, such as surface plasma …

An interstitial atom placed in a close-packed atomic row of a crystal is called crowdion. Such
defects are highly mobile; they can move along the row, transferring mass and energy. We …

The Frenkel-Kontorova chain with a free end is used to study initiation and propagation of
crowdions (antikinks) caused by impact of a molecule consisting of K atoms. It is found that …

A major issue of in-situ radiation damage studies is related to the influence of free surfaces.
Free surfaces in thin foils are indeed strong sinks for radiation-induced defects …

For the first time, the class of simple N-crowdions is expanded to M× N-crowdions, dynamics
of which is investigated in two-dimensional triangular Morse lattice by means of molecular …

In the quest of radiation and oxidation-resistant materials for the fuel claddings of nuclear
power stations, chromium (Cr) emerges as a good candidate. It shows a significantly lower …

An interstitial atom placed in a close‐packed atomic row of a crystal is called crowdion. Such
defects are highly mobile, they can move along the row transporting mass and energy. In the …
