This paper reviews the mechanisms underlying visible light detection based on phototransistors fabricated using amorphous oxide semiconductor technology. Although this family of materials is… Expand
Gated three-terminal device architecture to eliminate persistent photoconductivity in oxide semiconductor photosensor arrays.
The composition of amorphous oxide semiconductors, which are well known for their optical transparency, can be tailored to enhance their absorption and induce photoconductivity for irradiation with… Expand
Selective propene epoxidation on immobilized au(6-10) clusters: the effect of hydrogen and water on activity and selectivity.
Epoxidation made easy: Subnanometer gold clusters immobilized on amorphous alumina result in a highly active and selective catalyst for propene epoxidation. The highest selectivity is found for gas… Expand
