New developments in IBIC for the study of charge transport properties of radiation detector materials

A study of charge transport properties in various radiation detector materials (Si, Si(Li), CdTe, GaAs, CVD and natural diamond) has become in recent years one of the major application s of the nuclear microprobe technique IBIC. In order to extend the capabilities of IBIC, further developments of the technique were considered. By changing the projectile type and energy, different sample layers in the range between one and several hundreds of microns can be imaged- A trigger signal from simultaneously detected secondary electrons or a transmitted ion enables time-resolved IBIC imaging to be carried out. Furthermore, simultaneous STIM imaging showing areal density distributions, can be essential for the interpretation of IBIC images.
