چکیده
We report on the extended infrared single-photon response of niobium nitride superconducting nanowires deposited by atomic layer deposition. The nanowire detectors are based 4.65 nm thick NbN, patterned into 100 meanders, and characterized at 2.5 K. verify sensitivity from 1310 to 2006 with saturated shorter wavelengths.

Single-photon detectors based on ultranarrow superconducting nanowires.
We report efficient single-photon detection (η = 20% at 1550 nm wavelength) with ultranarrow (20 and 30 nm wide) superconducting nanowires, which were shown to be more robust to constrictions and more responsive to 1550 nm wavelength photons than standard superconducting nanowire single-photon detectors, based on 90 nm wide nanowires. We also improved our understanding of the physics of superco...
متن کاملUltimate sensitivity of superconducting single-photon detectors in the visible to infrared range
We present our quantum efficiency (QE) and noise equivalent power (NEP) measurements of the meandertype ultrathin NbN superconducting single-photon detector in the visible to infrared radiation range. The nanostructured devices with 3.5-nm film thickness demonstrate QE up to ~10% at 1.3 – 1.55 μm wavelength, and up to 20% in the entire visible range. The detectors are sensitive to infrared radi...
متن کاملMolecular beam epitaxial growth of gallium nitride nanowires on atomic layer deposited aluminum oxide
Semiconductor nanowires have received increasing focus from researchers due to their one dimensional characteristics, which offer new horizons for device designs. Nanowire growth has been shown to yield crystalline material on non-lattice matched substrates. Concerning gallium nitride nanowires, common growth substrates have been silicon (100) and (111) substrates. This manuscript discusses the...
متن کاملEffective Surface Passivation of InP Nanowires by Atomic-Layer-Deposited Al2O3 with POx Interlayer
III/V semiconductor nanostructures have significant potential in device applications, but effective surface passivation is critical due to their large surface-to-volume ratio. For InP such passivation has proven particularly difficult, with substantial depassivation generally observed following dielectric deposition on InP surfaces. We present a novel approach based on passivation with a phosph...
متن کاملAtomic layer deposited high-k nanolaminate capacitors
Al2O3–Ta2O5 nanolaminate films were prepared via atomic layer deposition (ALD) on silicon with a single overall composition and thickness, but with a varying number of Al2O3/Ta2O5 bilayers. The composition of the films was roughly 57% Al2O3 and 43% Ta2O5 and the total film thickness was held at 58 nm, while the number of bilayers was varied from 3 to 192 by changing the target bilayer thickness...
