Abstract
Charge collection, trapping and release processes are investigated by spectrally resolved photocurrent measurements in unintentionally doped, single crystal diamond samples with different contact structures: planar (i.e., metal contacts on the top and bottom sides) and laser-formed three dimensional (3D) graphitic contacts. Under high energy pulsed X-ray excitation, charge releasing effects are observed, whose contribution affects the response linearity of the 3D detector, which can be recovered using a suitable photo-signal acquisition through a proper detection electronics.
