ABSTRACT
The effects of applied oxide field and H[sup +] concentration on the transport of mobile protons across a buried oxide layer are examined in hydrogenated Unibond material. The H+ travel slower when moving from the substrate Si/SiO[sub 2] to the top Si/SiO[sub 2] interfaces than in the opposite direction. The effect of the self-field due to H[sup +] in the oxide is insignificant even when that field is larger than the applied field. These results suggest that detrapping from defects near the Si/SiO[sub 2] interfaces plays a critical role in the H[sup +] transport. © 2000 American Institute of Physics.
