The generalized stacking fault (GSF) energy surfaces of (110), (101), (121), (001), and(100) planes in -Sn are analyzed using first-principles density functional theory calculations. Fromthe minimum energy paths (MEPs) on the GSF energy surfaces analyzed, energetically preferableslip paths of 13 nonequivalent slip systems in -Sn are investigated. It is found that the MEP of(110)[111]/2, (101)[010], (101)[111]/2, (121)[101], and (121)[111]/2 deviates from the straight linepath and takes a curve line path. The results indicate that perfect dislocations on these five slip systemsdissociate into partial dislocations as in cubic and hexagonal crystals.
