Abstract: A thin-film transistor comprises an annealed layer comprising crystalline zinc oxide. A passivation layer is adjacent to the thin-film transistor. The passivation layer has a thickness and material composition such that when a dose of radiation from a radiation source irradiates the thin-film transistor, a portion of the dose that includes an approximate maximum concentration of the dose is located within the annealed layer. The annealed layer has a thickness and threshold displacement energies after it has been annealed such that: a) a difference between a transfer characteristic value of the thin-film transistor before and after the dose is less than a first threshold; and b) a difference between a transistor output characteristic value of the thin-film before and after the dose is less than a second threshold. The thresholds are based on a desired performance of the thin-film transistor.

Abstract: In at least one illustrative embodiment, a field-effect transistor biosensor for detection of a pathogen includes a substrate and a channel formed from a two-dimensional monolayer or few-layer metal chalcogenide that is functionalized with a biorecognition element. The biorecognition element may be an antibody, such as an antibody for the SARS-CoV-2 spike protein. A method for manufacturing the biosensor includes depositing an amorphous two-dimensional material on the substrate with pulsed laser ablation, crystallizing the amorphous two-dimensional material to generate a two-dimensional monolayer coupled to the substrate, and activating a surface of the two-dimensional material with the biorecognition element after crystallizing the amorphous two-dimensional material. The composition of the two-dimensional material may be tuned. The substrate may be photolithographically patterned. Other embodiments are described and claimed.

Abstract: A quantum charge parametron (QCP) includes a load capacitor; two quantum phase-slip junctions (QPSJs) coupled to each other through the load capacitor so as to define two charge islands, each charge island being located between the load capacitor and a respective one of the two QPSJs; at least one input voltage source coupled to the two QPSJs so that the two QPSJs, the load capacitor and the at least one input voltage source define a loop; and an excitation voltage source coupled to the two charge islands through first and second capacitors, respectively.

Abstract: One or more dielectric barriers, such as, but not limited to, aluminum oxide (Al2O3), is used to isolate and protect super conductive (SC) structures. The SC structures are formed from SC materials, such as, but not limited to, niobium, from other surrounding materials. Using the barriers significantly reduces and/or eliminates the degradation of the superconducting properties of the SC structures during subsequent fabrication steps that employ elevated temperatures. As a result, incorporation of the barriers relaxes the need to use lower temperature fabrication processes and opens up possibilities for use of different more desirable processes and/or materials during subsequent fabrication steps.

The one or more QPSJs are adapted for receiving at least one input and responsively providing at least one output. Each QPSJ is configured such that when an input voltage of an input voltage pulse exceeds a critical value, a quantized charge of a Cooper electron pair tunnels across said QPSJ as an output, when the input voltage is less than the critical value, no quantized charge of the Cooper electron pair tunnels across said QPSJ as the output, wherein the presence and absence of the quantized charge that is realizable as a constant area of current pulses in the output form two logic states, and wherein the at least one QPSJ is biased with a bias voltage. The superconducting circuit device may include one or more JJs.

Abstract: An electro-optical analog-to-digital converter having an enhanced effective sample rate. Several embodiments of the electro-optical analog-to-digital converter (10, 100, 150, and 200) are described, each involving either space-division demultiplexing, time-division demultiplexing, or wavelength-division demultiplexing to increase the effective sample rate at which an analog signal provided by a source (36) can be converted to a digital signal using electrical analog-to-digital converters (66). A plurality of light pulses having a constant amplitude are modulated in response to the analog signal and demultiplexed using one of the three different techniques, so that the analog signal is sampled at successive points in time, varying the intensity of light pulses passing through each modulator channel (32, 104).
