Title: Total Ionizing Dose Effects on Ge Channel $p$FETs with Raised $${\rm Si}_{0.55}{\rm Ge}_{0.45}$$ Source/Drain

Abstract

Here, the total ionizing dose response of Ge channel pFETs with raised Si 0.55Ge 0.45 source/drain is investigated under different radiation bias conditions. Threshold-voltage shifts and transconductance degradation are noticeable only for negative-bias (on state) irradiation, and are mainly due to negative bias-temperature instability (NBTI). Nonmonotonic leakage changes during irradiation are observed, which are attributed to the competition of radiation-induced field transistor leakage and S/D junction leakage.
