Abstract: An apparatus, system, and method for detecting light having a specified or first wavelength. The apparatus includes a substrate that generates charge separation in the presence of light having the first wavelength. An active material is deposited onto the substrate. The active material is configured to conduct current in the presence of light having a second wavelength. Two electrodes are connected to the active material. Light having the second wavelength is constantly applied to the active material and the current is monitored via the electrodes. The active material will conduct zero or minimal current via the electrodes if the substrate does not generate charge separation. Detection the presence of light having the first wavelength may be detected upon the detection of current via the two electrodes. The first wavelength may be non-visible light and the second wavelength may be visible light.

Abstract: An optically gated transistor (OGT) device that may be used as a selector device for one or more variable resistive memory devices. The OGT device isolates the one or more variable resistive memory devices when the OGT is not optically activated. The amount of current conducted by the OGT device is dependent on an intensity of light optically applied to the OGT device. The OGT device includes alternating layers of germanium selenide (GeSe) and GeSe plus an additional element deposited on a substrate. The OGT device includes only two electrodes connected to the alternating layers deposited on the substrate. The OGT device may generate an amplified electrical signal with respect to the magnitude of a received optical signal. The OGT device may be used to generate an optical signal having a different wavelength than the wavelength of a received optical signal.

Abstract: A conjugated polymer layer with a built-in diode is formed by providing a first metal-chalcogenide layer over a bottom electrode. Subsequently, a second metal-chalcogenide layer is provided over and in contact with the first metal-chalcogenide layer. The first metal-chalcogenide layer has a first conductivity type and the second metal-chalcogenide layer has a second conductivity type. The plane of contact between the first and second metal-chalcogenide layers creates the p-n junction of the built-in diode. Then a polymer layer is selectively deposited on the second metal-chalcogenide layer. The second metal-chalcogenide layer provides ions to the polymer layer to change its resistivity. A top electrode is then provided over the polymer layer. An exemplary memory cell may have the following stacked structure: first electrode/n-type semiconductor/p-type semiconductor/conjugated polymer/second electrode.
