A size-selected Ar gas cluster ion beam (GCIB) was applied to the SIMS of a polystyrene thin film. The size of Ar cluster ions are selected between 5000 to 500 atoms at an acceleration voltage of 5 and 10 kV using time-of-flight technique. Under t...

A size-selected argon (Ar) gas-cluster ion beam (GCIB) was applied to the secondary ion mass spectrometry (SIMS) of a 1,4-didodecylbenzene (DDB) thin film. The samples were also analyzed by SIMS using an atomic Ar(+) ion projectile and X-ray photo...
The formation of a nanopore in a graphene sheet by collision with an argon cluster is simulated using molecular dynamics method. The number of removed carbon atoms and the size of the nanopore are obtained as a function of the kinetic energy of th...
