“…Past proposals therefore focused on quasi-deterministic sources of entangled photon pairs, which can in principle be realized using individual emitters such as atoms or quantum dots [14], or by combining parametric downconversion with strong nonlinearities [15]. While many of these approaches seem promising in the longer term, they all pose significant practical challenges in the short and medium term.…”

Conventional wisdom suggests that realistic quantum repeaters will require quasi-deterministic sources of entangled photon pairs. In contrast, we here study a quantum repeater architecture that uses simple parametric down-conversion sources, as well as frequency-multiplexed multimode quantum memories and photon-number resolving detectors. We show that this approach can significantly extend quantum communication distances compared to direct transmission. This shows that important trade-offs are possible between the different components of quantum repeater architectures.

“…Here, we present an NP/NM synthesis platform based on an acoustofluidic (i.e., the fusion of acoustics and microfluidics) strategy for rapid, adaptable, and complete mixing of reagents. Our acoustofluidic device actively blends reagents together utilizing acoustic streaming induced by the oscillation of sharp‐edge structures in the microchannel.…”

Synthesis of nanoparticles and particulate nanomaterials with tailored properties is a central step toward many applications ranging from energy conversion and imaging/display to biosensing and nanomedicine. While existing microfluidics‐based synthesis methods offer precise control over the synthesis process, most of them rely on passive, partial mixing of reagents, which limits their applicability and potentially, adversely alter the properties of synthesized products. Here, an acoustofluidic (i.e., the fusion of acoustic and microfluidics) synthesis platform is reported to synthesize nanoparticles and nanomaterials in a controllable, reproducible manner through acoustic‐streaming‐based active mixing of reagents. The acoustofluidic strategy allows for the dynamic control of the reaction conditions simply by adjusting the strength of the acoustic streaming. With this platform, the synthesis of versatile nanoparticles/nanomaterials is demonstrated including the synthesis of polymeric nanoparticles, chitosan nanoparticles, organic–inorganic hybrid nanomaterials, metal–organic framework biocomposites, and lipid‐DNA complexes. The acoustofluidic synthesis platform, when incorporated with varying flow rates, compositions, or concentrations of reagents, will lend itself unprecedented flexibility in establishing various reaction conditions and thus enable the synthesis of versatile nanoparticles and nanomaterials with prescribed properties.

“…Different values, ranging from 5 to 110 cm 2 /V s, were reported for the electron mobility in ZnO and in ZnO:Sb. 9,15,39 The calculated majority charge carriers concentration in the above range is too low for Sb doping to 5 at. % if all Sb atoms are acting as donors.…”

“…3,4 In order to establish reliable p-type doping of ZnO, special attention has been focused on the group-V elements, including N, P, As, and Sb, due to the possibility of creating p-type conduction. Although p-type behavior has been reported by different research groups for these doped elements, especially Sb-doped ZnO (ZnO:Sb), [5][6][7][8][9][10][11] stability and reproducibility of the Sb doped p-type conductivity are still under question. Moreover, the electrical properties change from p-type to n-type, as the Sb content decreases in the ZnO:Sb thin films.…”

The charge carriers type in antimony-doped ZnO (ZnO:Sb) microwires was studied using the hot probe technique. The wires were grown by a simple thermal evaporation method. Contrary to the expected p-type behavior reported for Sb doped ZnO thin films and nanowires, our hot probe measurements of representative single Sb-doped ZnO wires show a stable n-type behavior. The hot probe technique is a simple and efficient way to determine the charge carrier type from thermoelectric measurements on a single semiconductor wire and could offer an alternative to Hall effect measurements. The technique relies on creating a temperature gradient across the wire (i.e., heating one side of the wire relative to the other) and monitoring the resulting open-circuit voltage between the two ends. We also performed Energy Dispersive X-ray Spectroscopy measurements to identify and monitor the elemental composition in these ZnO:Sb wires.
