abstract = {The presence of large densities of electrically active
defects is still an unsolved issue for future
high-mobility/high-k CMOS device technologies. This relates
to degraded device performance and reliability. Regrettably,
conventional admittance-based characterization techniques
often fail when applied to non-Si based devices. Among
others, enhanced generation of minority carriers and much
longer defect time constants make their results inaccurate.
Rather than of seeking to adapt commonly-used techniques, we
instead aim at direct measuring the semiconductor surface
potential by means of the Saturation surface PhotoVoltage
(SPV) technique. This approach allows for a DIT estimation
which is not limited by the trap response time or hindered
by minority carrier generation. Moreover, the DIT can be
estimated over the whole bandgap regardless of sample doping
type. We here report several case studies in support of the
proposed approach. We will also show that SPV can be applied
for the characterization of multi-layered Ge and III-V
devices incorporating high-k insulators.},
