Abstract: An apparatus, methods, and a system for a photonic biosensor are disclosed. The photonic biosensor includes a substrate having a sample addition zone in fluid communication with a wicking zone and a sample detection zone. The substrate also includes an optical input port configured to optically couple to a light source and an optical output port configured to optically couple to a light detector. The photonic biosensor also includes a photonic integrated circuit (“PIC”) connected to the substrate. The PIC includes a first grating coupler aligned with the optical input port, a second grating coupler aligned with the optical output port, at least one waveguide between the first grating coupler and the second grating coupler, and at least one detection element disposed within the at least one waveguide.

Abstract: A selector device includes a first electrode composed of a first metal having a first work function. A second electrode is composed of a second metal having a second work function. A selector layer is disposed between the first and second electrodes and is composed of a dielectric material having a conduction band and a valence band defining a band gap of at least 5 electron volts. Dopant atoms are disposed in the selector layer to form a sub-conduction band that is below the conduction band and above the work functions. When a threshold voltage is applied across the first and second electrodes, and a magnitude of the threshold voltage exceeds an energy difference between the sub-conduction band and the work functions, but does not exceed an energy difference between the conduction band and the work functions, an on-current will conduct through the selector layer.

Abstract: The performance of a ReRAM structure may be stabilized by utilizing a dry chemical gas removal (or cleaning) process to remove sidewall residue and/or etch by-products after etching the ReRAM stack layers. The dry chemical gas removal process decreases undesirable changes in the ReRAM forming voltage that may result from such sidewall residue and/or etch by-products. Specifically, the dry chemical gas removal process may reduce the ReRAM forming voltage that may otherwise result in a ReRAM structure that has the sidewall residue and/or etch by-products. In one embodiment, the dry chemical gas removal process may comprise utilizing a combination of HF and NH3 gases. The dry chemical gas removal process utilizing HF and NH3 gases may be particularly suited for removing halogen containing sidewall residue and/or etch by-products.
