Abstract: Based on the classical molecular processes of He atom into SWCNT with wall dynamics method and TLHT potential model, the injection defects of different radius are studied. The calculated results indicate that there are four typical moving patterns of He atom with different injective energy and the size of wall defects make a great difference to the absorption and storage behavior of He into SWNT.
