Abstract
Ca-implantation is used to enhance SnO2-sensor signal stability. Ca do pants compensate conductivity reduction by oxygen diffusion into bulk oxygen vacancies at certain operating temperatures. Sensor signal drif ts are reduced significantly. A temperature control with calibration c ycles is proposed to run metaloxide sensor systems almost free of drif t.
