We present a source of entangled photons that violates Bell inequality free the "fair-sampling" assumption, by over 7 standard deviations. This violation is first reported experiment with to close detection loophole, and we demonstrate enough "efficiency" overhead eventually perform fully loophole-free test local realism. The entanglement quality verified maximally violating additional tests, testing upper limit quantum correlations. Finally, use generate "device-independent" private random...

Al(2)O(3) and TiO(2) atomic layer deposition (ALD) were employed to develop an ultrathin barrier film on copper prevent water corrosion. The strategy was utilize ALD as a pinhole-free protect the using ALD. An initial set of experiments performed at 177 °C establish that could nucleate produce high-quality film. In situ quartz crystal microbalance (QCM) measurements verified nucleated grew efficiently copper-plated crystals trimethylaluminum (TMA) reactants. electroplating technique also...

Energy bandgap largely determines the optical and electronic properties of a semiconductor. Variable therefore makes versatile functionality possible in single material. In layered material black phosphorus, can be modulated by number layers; as result, few-layer phosphorus has discrete values that are relevant for opto-electronic applications spectral range from red, monolayer, to mid-infrared bulk limit. Here, we further demonstrate continuous modulation mechanical strain applied through...

With the scaling limits of silicon-based MOS technology, critical and challenging issue is to explore more alternative materials improve performance devices. Two-dimensional (2D) semiconductor WSe2 with a proper band gap inherent stability under ambient conditions makes it potential channel material for realizing new generation field-effect transistors (FETs). In light low on-state current experimental sub-10 nm 2D MoS2 FETs, we limitation monolayer (ML) device by using accurate ab initio...

Magnetic polarization reduces spin scattering and underpins colossal magnetoresistance (CMR) in the manganites almost all other CMR materials. In sharp contrast, observed ferrimagnetic insulator Mn${}_{3}$Si${}_{2}$Te${}_{6}$, which features a resistivity drop by an astonishing seven orders of magnitude, emerges only when fully polarized magnetization is avoided. This intriguing type electrical transport fits no existing theoretical models, providing new paradigm for studying its applications.
