Abstract: Aspects of the subject disclosure may include, for example, a photodetecting device that includes a bottom gate, a bilayer semiconductor formed on the bottom gate, and a top gate above the bilayer semiconductor comprising a polymer electrolyte. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, obtaining a first vector comprising a first plurality of parameters, determining a vector difference between the first plurality of parameters and a second plurality of parameters of a second vector, responsive to the determining, computing a first weighted vector distance based on the vector difference, providing a first representation of the first weighted vector distance to at least one bus, obtaining a second representation of a second weighted vector distance from the at least one bus, comparing the second representation of the second weighted vector distance to the first representation of the first weighted vector distance, and responsive to determining that the second representation of the second weighted vector distance matches the first representation of the first weighted vector distance based on the comparing, setting a first indicator to indicate a first match. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, applying a setting voltage across first and second electrodes, wherein a nanowire with a first electrical resistance is electrically connected between the first and second electrodes, wherein the applying of the setting voltage causes a migration of ions from the first and/or second electrodes to a surface of the nanowire, and wherein the migration of ions effectuates a reduction of electrical resistance of the nanowire from the first electrical resistance to a second electrical resistance that is lower than the first electrical resistance; and applying a reading voltage across the pair of electrodes, wherein the reading voltage is less than the setting voltage, and wherein the reading voltage is sufficiently small such that the applying of the reading voltage causes no more than an insignificant change of the electrical resistance of the nanowire from the second electrical resistance. Other embodiments are disclosed.
