Study of morphological behavior of single diamond crystals
Abstract
Isolated diamond crystals are grown by hot filament chemical vapor deposition (CVD) on Si-substrates without nucleation enhancement. We investigate the development of isolated diamond crystals under changing growth conditions. The growth parameter α= 3v 1 0 0 /v 1 1 1 is determined from isolated diamond crystals and the same crystal is regrown several times and detected repeatedly by a scanning electron microscope. The change in morphology can be followed as the growth conditions are changing. Multiply twinned particles are also investigated and observed to change their morphology with the growth parameter α. The dependence of the idiomorphic shape on the growth parameter α is measured experimentally and compared with model calculations. It is shown that the basic determination of the morphology of a multiply twinned particle occurs at the early part of the nucleation phase.
