Query: Lateral IBIC characterization of single crystal synthetic diamond
  detectors   In order to evaluate the charge collection efficiency (CCE) profile of
single-crystal diamond devices based on a p type/intrinsic/metal configuration,
a lateral Ion Beam Induced Charge (IBIC) analysis was performed over their
cleaved cross sections using a 2 MeV proton microbeam. CCE profiles in the
depth direction were extracted from the cross-sectional maps at variable bias
voltage. IBIC spectra relevant to the depletion region extending beneath the
frontal Schottky electrode show a 100% CCE, with a spectral resolution of about
1.5%. The dependence of the width of the high efficiency region from applied
bias voltage allows the constant residual doping concentration of the active
region to be evaluated. The region where the electric field is absent shows an
exponentially decreasing CCE profile, from which it is possible to estimate the
diffusion length of the minority carriers by means of a drift-diffusion model.
