  Title Spectral dependency of superconducting single photon detectors Type Journal Article
  Year 2010 Publication (up) J. Appl. Phys. Abbreviated Journal J. Appl. Phys.  
  Volume 107 Issue 11 Pages 116103 (1 to 3)  
  Keywords NbN SSPD, SNSPD  
  Abstract We investigate the effect of varying both incoming optical wavelength and width of NbN nanowires on the superconducting single photon detectors (SSPD) detection efficiency. The SSPD are current biased close to critical value and temperature fixed at 4.2 K, far from transition. The experimental results are found to verify with a good accuracy predictions based on the “hot spot model,” whose size scales with the absorbed photon energy. With larger optical power inducing multiphoton detection regime, the same scaling law remains valid, up to the three-photon regime. We demonstrate the validity of applying a limited number of measurements and using such a simple model to reasonably predict any SSPD behavior among a collection of nanowire device widths at different photon wavelengths. These results set the basis for designing efficient single photon detectors operating in the infrared (2–5 μm range).

  Title Rapid thermal annealing of ZnO thin films grown at room temperature Type Journal Article
  Year 2010 Publication (up) J. Vac. Sci. Technol. A Abbreviated Journal  
  Volume 28 Issue 2 Pages 4  
  Keywords Annealing  
  Abstract The authors successfully obtained high quality ZnO thin films by growing them at room temperature (RT) and postannealing by rapid thermal annealing (RTA). The thin films were grown by pulsed laser deposition on Si (100) substrates at RT, and RTA was performed under various temperatures and ambient conditions. Based on the UV emission to visible emission ratio in RT photoluminescence (PL) spectra, the optimum film was obtained at annealing temperature ~700 °C in an ambient of Ar, N2, or O2 at 0.1 Torr, while the optimum annealing temperature was above 1100 °C in the air ambient at atmospheric pressure. The morphology and structure of the films in different RTA conditions were investigated by using field emission scanning electron microscopy and grazing incidence x-ray diffraction, and were discussed in conjunction with the PL data.

  Title On-Chip Single Plasmon Detection Type Journal Article
  Year 2010 Publication (up) Nano Letters Abbreviated Journal Nano Lett.  
  Volume 10 Issue Pages 661-664  
  Keywords optical antennas; SSPD; Single surface plasmons; superconducting detectors; semiconductor quantum dots; nanophotonics  
  Abstract Surface plasmon polaritons (plasmons) have the potential to interface electronic and optical devices. They could prove extremely useful for integrated quantum information processing. Here we demonstrate on-chip electrical detection of single plasmons propagating along gold waveguides. The plasmons are excited using the single-photon emission of an optically emitting quantum dot. After propagating for several micrometers, the plasmons are coupled to a superconducting detector in the near-field. Correlation measurements prove that single plasmons are being detected.

  Title Experimental EPR-steering using Bell-local states Type Journal Article
  Year 2010 Publication (up) Nat. Phys. Abbreviated Journal Nat. Phys.  
  Volume 6 Issue 11 Pages 845-849  
  Keywords fromIPMRAS  
  Abstract The concept of `steering' was introduced in 1935 by Schrödinger as a generalization of the EPR (Einstein-Podolsky-Rosen) paradox. It has recently been formalized as a quantum-information task with arbitrary bipartite states and measurements, for which the existence of entanglement is necessary but not sufficient. Previous experiments in this area have been restricted to an approach that followed the original EPR argument in considering only two different measurement settings per side. Here we demonstrate experimentally that EPR-steering occurs for mixed entangled states that are Bell local (that is, that cannot possibly demonstrate Bell non-locality). Unlike the case of Bell inequalities, increasing the number of measurement settings beyond two-we use up to six-significantly increases the robustness of the EPR-steering phenomenon to noise.

  Title ‘Soft’ Au, Pt and Cu contacts for molecular junctions through surface-diffusion-mediated deposition Type Journal Article
  Year 2010 Publication (up) Nature Nanotechnology Abbreviated Journal Nat. Nanotech.  
  Volume 5 Issue 8 Pages 612–617  
  Keywords  
  Abstract Virtually all types of molecular electronic devices depend on electronically addressing a molecule or molecular layer through the formation of a metallic contact. The introduction of molecular devices into integrated circuits will probably depend on the formation of contacts using a vapour deposition technique, but this approach frequently results in the metal atoms penetrating or damaging the molecular layer. Here, we report a method of forming 'soft' metallic contacts on molecular layers through surface-diffusion-mediated deposition, in which the metal atoms are deposited remotely and then diffuse onto the molecular layer, thus eliminating the problems of penetration and damage. Molecular junctions fabricated by this method exhibit excellent yield (typically >90%) and reproducibility, and allow examination of the effects of molecular-layer structure, thickness and contact work function.

  Title High-yield self-limiting single-nanowire assembly with dielectrophoresis Type Journal Article
  Year 2010 Publication (up) Nature Nanotechnology Abbreviated Journal Nat. Nanotech.  
  Volume 5 Issue 7 Pages 525–530  
  Keywords  
  Abstract Single-crystal nanowire transistors and other nanowire-based devices could have applications in large-area and flexible electronics if conventional top-down fabrication techniques can be integrated with high-precision bottom-up nanowire assembly. Here, we extend dielectrophoretic nanowire assembly to achieve a 98.5% yield of single nanowires assembled over 16,000 patterned electrode sites with submicrometre alignment precision. The balancing of surface, hydrodynamic and dielectrophoretic forces makes the self-assembly process controllable, and a hydrodynamic force component makes it self-limiting. Our approach represents a methodology to quantify nanowire assembly, and makes single nanowire assembly possible over an area limited only by the ability to reproduce process conditions uniformly.

  Title Nanostructured materials for photon detection Type Journal Article
  Year 2010 Publication (up) Nature Nanotechnology Abbreviated Journal Nat. Nanotech.  
  Volume 5 Issue 6 Pages 391–400  
  Keywords  
  Abstract The detection of photons underpins imaging, spectroscopy, fibre-optic communications and time-gated distance measurements. Nanostructured materials are attractive for detection applications because they can be integrated with conventional silicon electronics and flexible, large-area substrates, and can be processed from the solution phase using established techniques such as spin casting, spray coating and layer-by-layer deposition. In addition, their performance has improved rapidly in recent years. Here we review progress in light sensing using nanostructured materials, focusing on solution-processed materials such as colloidal quantum dots and metal nanoparticles. These devices exhibit phenomena such as absorption of ultraviolet light, plasmonic enhancement of absorption, size-based spectral tuning, multiexciton generation, and charge carrier storage in surface and interface traps.
