Popis: The objective of this article is to add to the experimental understanding of the relationship between the electrical properties of diamond and the growth input and output parameters. A wide selection of thin polycrystalline CVD diamond is investigated using the impedance spectroscopy (IS) modelling technique. The films are analyzed in the as-grown and annealed states. As part of this task, the as-grown dc resistivity of the films is correlated to four growth output parameters: average grain size, full width half maximum (FWHM), diamond to graphite signal ratio, and growth parameter, . In addition, the ac properties are analyzed in terms of a developed ac circuit model. Also investigated in this study are the annealing and temperature effects on electrical conductivity and ac circuit model parameters for as-grown and annealed diamond films.
