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: “Control of zinc oxide nanowire array properties with electron-beam lithography templating for photovoltaic applications” accepted to Nanotechnology

New paper: “Control of zinc oxide nanowire array properties with electron-beam lithography templating for photovoltaic applications” accepted to Nanotechnology

Feb 3, 2015 | News Articles, Our Research

[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...
24-picosecond single-photon timing jitter in saturated SNSPDs – New Paper in IEEE Quantum Electronics

24-picosecond single-photon timing jitter in saturated SNSPDs – New Paper in IEEE Quantum Electronics

Jan 7, 2015 | News Articles, Our Research

In our new paper, to appear in the IEEE Jornal of Selected Topics in Quantum Electronics (JSTQE), we have demonstrated fully-saturated nanowire single-photon detectors with 24 ps jitter. Furthermore we show an improved fabrication process that allowed us to increase...
New paper: “Universal scaling of the critical temperature for thin films near the superconducting-to-insulating transition” accepted to Phys. Rev. B

New paper: “Universal scaling of the critical temperature for thin films near the superconducting-to-insulating transition” accepted to Phys. Rev. B

Dec 17, 2014 | News Articles, Our Research

[preprint] [supp. info.] We reported that the superconducting properties scale universally close to the superconducting-to-insulating transition in thin films. This universal behavior was found useful not only for the fundamental understanding of superconductivity...
New paper: “High-Yield, Ultrafast, Plasmon-Enhanced Au Nanorod Optical Field Emitter Arrays” accepted to ACS Nano

New paper: “High-Yield, Ultrafast, Plasmon-Enhanced Au Nanorod Optical Field Emitter Arrays” accepted to ACS Nano

Nov 11, 2014 | News Articles, Our Research

[abstract] Here we demonstrate the design, fabrication and characterization of ultrafast, surface-plasmon enhanced Au nanorod optical field emitter arrays. We present a quantitative study of electron emission from Au nanorod arrays fabricated by high-resolution...
New paper: “Eight-fold signal amplification of a superconducting nanowire single-photon detector using a multiple-avalanche architecture” accepted to Optics Express

New paper: “Eight-fold signal amplification of a superconducting nanowire single-photon detector using a multiple-avalanche architecture” accepted to Optics Express

Oct 20, 2014 | News Articles, Our Research

[pdf] [abstract] Superconducting nanowire avalanche single-photon detectors (SNAPs) with n parallel nanowires are advantageous over single-nanowire detectors because their output signal amplitude scales linearly with n. However, the SNAP architecture has not been...
