Abstract
The directions of preferential growth of free-standing optical-quality CVD diamond wafers have been investigated with the help of electron paramagneti c resonance (EPR). EPR signals of the well-known P1 centre (substitutional nitrogen) have been used as a probe. A computer simulation of EPR spectra o f preferentialty oriented polycrystalline material allows the estimation of the real orientation and spatial distribution of crystallographic axes of crystallites in the samples oriented preferentially in the [110] direction.
