Recent Results from Polycrystalline CVD Diamond Detectors
RD42 Collaboration, L. Bäni, A. Alexopoulos +109
Diamond is a material in use at many nuclear and high energy facilities due to its inherent radiation tolerance and ease of use. We have characterized detectors based on chemical v…
Formation of buried conductive micro-channels in single crystal diamond with MeV C and He implantation
F. Picollo, P. Olivero, F. Bellotti +6
As demonstrated in previous works, implantation with a MeV ion microbeam through masks with graded thickness allows the formation of conductive micro-channels in diamond which are…
Semiconductor characterization by scanning ion beam induced charge (IBIC) microscopy
E. Vittone, Z. Pastuovic, P. Olivero +5
The acronym IBIC (Ion Beam Induced Charge) was coined in early 1990's to indicate a scanning microscopy technique which uses MeV ion beams as probes to image the basic electronic p…
Finite element analysis of ion-implanted diamond surface swelling
F. Bosia, P. Olivero, E. Vittone +10
We present experimental results and numerical Finite Element analysis to describe surface swelling due to the creation of buried graphite-like inclusions in diamond substrates subj…
