Find radiation-tolerant materials before they fail in orbit.
Radiation-Hard Materials Screener
Identify wide-bandgap oxides, nitrides, and ceramics that combine high displacement-damage threshold energies with low defect formation rates — screening the full Lattice Graph corpus for candidates suited to space, defense, and nuclear environments. Endpoint: GET /v1/discovery/radiation-hard.
Key outcomes
What goes in
Inputs this feature expects
- Target radiation environment (TID, displacement damage, proton fluence)
- Operating temperature and bandgap requirements
- Optional crystal structure constraints (perovskite, spinel, corundum, etc.)
What comes out
Outputs your team can act on
- Ranked candidates with bandgap, defect formation energy, and radiation tolerance metrics
- Comparison against radiation-hard benchmarks (sapphire, SiC, GaN)
- Patent landscape check for each shortlisted candidate
Workflow
How teams use Radiation-Hard Materials Screener
Define the radiation environment
Specify total ionizing dose limits, displacement damage thresholds, and operating temperature bounds for the target mission.
Screen the candidate space
Lattice Graph filters 13M+ structures for wide-bandgap oxides and nitrides, then cross-checks DFT defect formation energies against the specified environment.
Validate and compare
Survivors are benchmarked against known radiation-hard materials and checked for patent conflicts before advancing to experimental validation.
Best fit
Where this feature adds the most leverage
- Aerospace and defense contractors qualifying materials for LEO, GEO, or deep-space missions
- Nuclear energy programs seeking radiation-tolerant structural ceramics
- Power electronics teams designing wide-bandgap devices for high-radiation environments
