Quantum dot optical devices with enhanced gain and sensitivity and methods of making same
Various embodiments include apparatuses including optical and optoelectronic devices and methods of making same. One such device includes an image sensor having an integrated circuit with a number of pixel electrodes, a substantially-continuous optically-sensitive layer, and at least one counter-electrode. The substantially continuous optically sensitive layer is in electrical communication with both the number of pixel electrodes and also the counter-electrode. Additional apparatuses and methods are disclosed.
1. An image sensor comprising:
an integrated circuit comprising a plurality of pixel electrodes;
a substantially-continuous optically-sensitive layer; and
at least one counter-electrode, the substantially continuous optically sensitive layer being in electrical communication with both the plurality of pixel electrodes and also the counter-electrode.
2. The image sensor of claim 1 , wherein the counter-electrode is coplanar with the plurality of pixel electrodes.
3. The image sensor of claim 1 , wherein the counter-electrode is on top of the optically-sensitive layer.
4. The image sensor of claim 1 , wherein the counter-electrode is optically opaque.
5. The image sensor of claim 1 , wherein the counter-electrode is optically transparent.
6. The image sensor of claim 1 , wherein the counter-electrode is substantially continuous.
