Abstract

The initial stages of (111)-oriented diamonds grown on Pt substrates have been studied by both scanning electron microscopy (SEM) and transmission electron microscopy (TEM). TEM images clearly reveal that scratching pretreatment strongly damages the surfaces of (111)-Pt substrates. After pretreatment, the column like polycrystalline damage layers are observed to form on the Pt surfaces for the first time, the average thickness of which is about 400 to 500 nm. During the subsequent deposition process, these surface damage layers gradually recrystallized into the single-crystalline state. The nucleation and initial growth of diamond particles are, in fact, accompaniedby the Pt surface recrystallization process, and the formation of the (111)-oriented diamond grains is discussed in regard to the Pt surface recrystallization process.
