Abstract: The triboelectric charging of natural diamond crystals as a result of the contact electrization on a metal surface has been experimentally studied. It is established that the contact electrization of diamond crystals is related to the accumulation of a positive charge due to the filling of hole traps with an activation energy of 1.1–2.17 eV. A physical model is proposed to describe this process. [ABSTRACT FROM AUTHOR]
