New Publication  “Superconducting Nanowire Spiking Element for Neural Networks ”

New Publication “Superconducting Nanowire Spiking Element for Neural Networks ”

Oct 7, 2020 | News Articles

As the limits of traditional von Neumann computing come into view, the brain’s ability to communicate vast quantities of information using low-power spikes has become an increasing source of inspiration for alternative architectures. Key to the success of these...
New Publication  “Fabrication of gold nanostructures using wet lift-off without adhesion promotion”

New Publication “Fabrication of gold nanostructures using wet lift-off without adhesion promotion”

Sep 4, 2020 | News Articles

The use of an intervening adhesion layer is essential in reliable fabrication of noble metallic nanostructures for optical and electronic devices. However, many emerging applications such as plasmonics and transfer printing raise the demand of metallic structures...
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: “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...
