  • FLEXIBLE AND MINIATURIZED COMPACT VERTICAL COLOR SENSOR
    Publication number: 20250031463
    Abstract: Various examples are provided related to color and optical sensing with vertically stacked sensors. In one example, a vertical color sensing element includes a R-sensing channel layer including a first sensing material, G-sensing channel layer including a second sensing material, and a B-sensing channel layer including a third sensing material. First and second transparent insulating layer having first and second thicknesses are between the R and G sensing channel layers and the G and B sensing channel layers, respectively. The first and second thicknesses can be based upon focal lengths of R-light, G-light and B-light entering the vertical color sensing device. In another example, a vertical optical sensor can include a first sensing channel layer including a first sensing material, a transparent insulating layer, and a second sensing channel layer including a second sensing material. The first sensing material can be vdW-S and the second sensing material can be different.

  • Charge coupled device based on atomically layered van der waals solid state film for opto-electronic memory and image capture
    Patent number: 9431565
    Abstract: An opto-electronic sensor may provide one or more layers of atomically layered photo-sensitive materials. The sensor may include a gate electrode layer, a dielectric layer in contact with the gate electrode layer, and a working media layer that is photo-sensitive deposited on the dielectric layer. The working media layer may provide one or more layers of one or more materials where each of the one or more layers is an atomic layer. The sensor may also include side electrodes in contact with the working media layer.
