摘要：

The effect of discharge current (I(d)) on the diamond structure has been investigated. The films deposited on A1 substrate at a low substrate temperature (T(s)) of about 200-degrees-C by DC plasma CVD are composed of ball-like grains containing microcrystalline diamond crystals with a hydrogenated amorphous component. When I(d) increases, the growth rate of the grains and the size of the diamond crystals increase, and the amorphous component decreases. These results show that the increase of I(d) enhances the diamond structure formation, in addition to the T(s) factor's well known effect on the formation of a definite diamond film.
