New Publication: “Large-Area Superconducting Nanowire Single-Photon Detectors for Operation at Wavelengths up to 7.4 μm”

New Publication: “Large-Area Superconducting Nanowire Single-Photon Detectors for Operation at Wavelengths up to 7.4 μm”

Jul 19, 2022 | News Articles

The optimization of superconducting thin-films has pushed the sensitivity of superconducting nanowire single-photon detectors (SNSPDs) to the mid-infrared (mid-IR). Earlier demonstrations have shown that straight tungsten silicide nanowires can achieve unity internal...

New publication: “A nanofabricated, monolithic, path-separated electron interferometer”

New publication: “A nanofabricated, monolithic, path-separated electron interferometer”

May 23, 2017 | News Articles, Uncategorized

We describe a modular, self-aligned, amplitude-division electron interferometer in a conventional transmission electron microscope. The interferometer consists of two 45-nm-thick silicon layers separated by 20 μm. This interferometer is fabricated from a...

New publication: “Single-photon imager based on a superconducting nanowire delay line”

Apr 14, 2017 | News Articles

We demonstrate a scalable single-photon imager using a single continuous superconducting nanowire that is not only a single-photon detector but also functions as an efficient microwave delay line. In this context, photon-detection pulses are guided in the nanowire and...
New publication: “A nanocryotron comparator can connect single-flux-quantum circuits to conventional electronics”

New publication: “A nanocryotron comparator can connect single-flux-quantum circuits to conventional electronics”

Mar 8, 2017 | News Articles, Uncategorized

We demonstrate the use of a single three-terminal superconducting-nanowire device, called the nanocryotron (nTron), as a digital comparator to combine SFQ circuits with mature semiconductor circuits such as complementary metal oxide semiconductor (CMOS) circuits....
New publication: “Photoemission from Plasmonic Nanoparticles”

New publication: “Photoemission from Plasmonic Nanoparticles”

Dec 21, 2016 | News Articles, Uncategorized

We demonstrate strong-field, carrier-envelope-phase-sensitive photoemission from arrays of tailored metallic nanoparticles, and we show the influence of the nanoparticle geometry and the plasmon resonance on the phase-sensitive response. Additionally, from a...

Sep 16, 2016 | News Articles, Uncategorized

Developing superconducting-nanowire based electronics We are looking for a graduate research assistant (must be an admitted MIT graduate student) to develop novel quantum sensors, logic devices and digital circuits based on superconducting nanowires. Present projects...
New Paper: “Designs for a quantum electron microscope”

New Paper: “Designs for a quantum electron microscope”

Mar 21, 2016 | News Articles, Our Research

One of the astounding consequences of quantum mechanics is that it allows the detection of a target using an incident probe, with only a low probability of interaction of the probe and the target. This ‘quantum weirdness’ could be applied in the field of electron...
New Paper: “Dimensional Tailoring of Hydrothermally Grown Zinc Oxide Nanowire Arrays”

New Paper: “Dimensional Tailoring of Hydrothermally Grown Zinc Oxide Nanowire Arrays”

Jan 13, 2016 | News Articles

Hydrothermally synthesized ZnO nanowire arrays are critical components in a range of nanostructured semiconductor devices. The device performance is governed by relevant nanowire morphological parameters that cannot be fully controlled during bulk hydrothermal...
