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

Journal 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

Journal 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,
