Abstract
Observations with a scanning electron microscope of the surfaces of graphite crystals, grown under conditions where an impurity is adsorbed at the surface, have shown the initial formation of holes having hexagonal geometry. These may be related to the impurity blocking of screw dislocations in a manner similar to that considered for whisker growth. Hole formation and whisker growth appear to be a function of the degree to which impurity atoms are adsorbed at a growth surface, and a hole formed under these conditions may be considered as a negative whisker.Keywords
