Summary
Heavy charged-particle (HCP) radiation can corrupt data in 3D optical memory. Information within nanometers of a particle
Area of Science:
- Materials Science
- Radiation Physics
- Data Storage Technologies
Background:
- Three-dimensional (3D) optical data storage offers high density.
- Understanding radiation effects is crucial for data integrity.
Purpose of the Study:
- To model the impact of heavy charged-particle (HCP) radiation on 3D optical memory.
- To identify the mechanisms of data loss due to HCP exposure.
Main Methods:
- Developed a simulation model incorporating HCP track dose distribution.
- Included thermal effects and matrix-specific radiation responses.
- Modeled photochromic molecule transition kinetics (bit flips).
Main Results:
- Simulations show potential information loss around the HCP track axis.
- Data corruption is dependent on the particle's track structure.
- A nanometer-scale volume around the track is susceptible to data loss.
Conclusions:
- HCP radiation poses a risk to stored information in 3D optical memory.
- The developed model provides insights into radiation-induced data degradation.
- Track structure is a key factor determining the extent of data loss.
