In this work charge trapping and electroluminescence (EL) quenching in rare-earth (RE) implanted SiO 2 on Si as a function of injected charge into the dielectric were studied. The blocking of the luminescent REO X nanoclusters from the hot exciting electrons by negative charge trapping in a ...

The authors of this paper attribute the higher conductivity at high temperatures to contributions of ionic conductivity. Basically, they say the oxygen atoms (ions) can move around in the material at such high temperatures and generate charge movement (conductivity) that way. (they also discuss the...
