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...

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...

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....

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...

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...

We built a transmissometer to determine the thickness of thin films of NbN that are deposited as the starting material for SNSPDs. The transmissometer measures the transmittance of light through NbN thin films, and the thickness of the NbN is found by fitting the...

[abstract] We found that electron-beam lithography, a top-down approach, is a suitable prototyping method for templating and controlling hydrothermally-grown ZnO nanowires (NWs). By varying the deposition method of the ZnO seed layer, annealing and template hole...
