Abstract
Polycrystalline CVD diamond samples have been prepared with different electrode configurations, allowing to produce an electric field parallel and perpendicular to the direction of the grain boundaries. A photon beam with an energy of 15 keV was used to study the response with a spatial resolution of about 7 μm. Results on the influence of the field direction on the signal, the pumping effect, and the signal response as a function of the film thickness were obtained.
Research highlights► Measurement of charge transport perpendicular to growth direction in pCVD diamond. ► Spatially resolved measurement of priming effect. ► Comparative study of charge collection with different electric field configurations.
