Research progress on the characterization of irradiation damage defects and performance control of titanium alloy

open access: yesJournal of Aeronautical Materials, 2022
Under the high-energy particle impingement and cascade effect, different types of radiation damage defects occur in metals. The aggregation and evolution of radiation damage defects can lead to the destruction of the internal structural stability and the

Improved buildup model for radiation-induced, defects in MOSFET isolation oxides

open access: yesJournal of Radiation Research and Applied Sciences, 2022
Ionizing radiation induces defects in STI oxides in current MOSFETs. These defects may degrade the performance of the MOS circuit. Analytical models for the buildup of these defects during the radiation exposure are available in literature. In this paper,

Effect of radiation-induced emission of Schottky defects on the formation of colloids in alkali halides [PDF]

open access: yes, 2003
Formation of vacancy clusters in irradiated crystals is considered taking into account radiation-induced Schottky defect emission (RSDE) from extended defects.

Are topological defects responsible for the 300 EeV cosmic rays? [PDF]

open access: yes, 1996
We use of a hybrid matrix--Monte Carlo method to simulate the cascade through the cosmic background radiation initiated by UHE particles and radiation emitted by topological defects.

Could the primordial radiation be responsible for vanishing of topological defects? [PDF]

open access: yes, 2017
We study the motion of topological defects in 1+1 and 2+1 d relativistic $\phi^6$ model with three equal vacua in the presence of radiation. We show that even small fluctuations can trigger a chain reaction leading to vanishing of topological defects ...
