Abstract
Both spiral growth and terrace flow growth were observed on the vicinal (11 1) faces of a multiply twinned diamond particle by scanning electron micros copy (SEM). Furthermore, both left- and right-handed spirals were obtained on a fivefold multiply twinned particle. The SEM results provide direct evi dence for which two types of growth modes could exist at the same time duri ng the chemical vapor deposition (CVD) diamond growth. It depends strongly on whether there exists a screw dislocation on the underlying diamond subst rate for each respective growth on (111) faces. We explained all the featur es using the classical crystal growth theory of Burton, Cabrera and Frank.
