Impact Statement & Explanation of Research:
There are three primary thrusts in Prof. Allain's Radiation Surface Science and Engineering Laboratory (RSSEL) group:
- The study of nuclear fusion and plasmas interacting with matter, where the plasma-material interface in advanced fusion devices is investigated by computational modeling and with experimental validation of fundamental processes. Work in this thrust includes: 1) lithiated graphite coatings, 2) liquid lithium systems, 3) advanced nanocrystalline refractory materials and 4) in-situ plasma-surface interaction diagnostics in major fusion machines.
- Directed radiation synthesis, includes the study of fundamental mechanisms of how radiation modifies low-dimensional state (e.g. nanostructures, ultrathin films, etc...) solid and liquid-state systems at the nanoscale. Several projects include: 1) compound semiconductor synthesis with ultra-low energy heavy-ion modification, 2) alkali doping on graphene, 3) advanced nanostructured magnetic stent synthesis and 4) ion-beam artificial texturing of ultra-thin films.
- Advanced in-situ probing and manipulating techniques at the nanoscale, consists of research that develops in-situ approaches at materials systems at the nanoscale modified by some form of energetic particle irradiation. For example hyper-thermal heavy-ions inducing self-organization at ultrashallow regions of compound semiconductors or semi-metals.
