A study of the charge collection properties of polycrystalline CVD diamond with synchrotron radiation

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 key was used to study the response with a spatial resolution o...

Sumario: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 key was used to study the response with a spatial resolution of about 7 mu m. 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. (C) 2011 Elsevier B.V.
