—In this letter, gate-all-around vertical nanowire (NW) polycrystalline silicon (poly-Si) thin-film transistors (TFTs) are demonstrated using a CMOS-compatible process. Both N-and P-TFT devices (with gate length down to 100 nm and a wire diameter of ∼30 nm) exhibit good transistor performance, e.g., high I on /I off ratio of > 10 6 , low subthreshold slope(More)
Modification of surface and bulk properties of solids by irradiation with ion beams is a widely used technique with many applications in material science. In this study, we show that nano-hillocks on CaF2 crystal surfaces can be formed by individual impact of medium energy (3 and 5 MeV) highly charged ions (Xe(22+) to Xe(30+)) as well as swift (kinetic(More)
Two types of solar cells are successfully grown on chips from two CMOS generations. The efficiency of amorphous-silicon (a-Si) solar cells reaches 5.2%, copper-indium-gallium-selenide (CIGS) cells 7.1%. CMOS functionality is unaffected. The main integration issues: adhesion, surface topography, metal ion contamination, process temperature, and mechanical(More)
Designing a lithium ion battery (LIB) with a three-dimensional device structure is crucial for increasing the practical energy storage density by avoiding unnecessary supporting parts of the cell modules. Here, we describe the superior secondary battery performance of the bulk all-solid-state LIB cell and a multilayered stacked bipolar cell with doubled(More)
Taxonomical analysis of two genetically distinguished Lactobacillus strains isolated from traditional Chinese fermented vegetables 'Suan cai' was performed. They formed L-lactate from glucose, were facultatively heterofermentative, and had a DNA G+C content of 53-54mol%. They fermented D- and L-arabinose. They produced lactate, ethanol and acetate from(More)
This work demonstrates a new type of SONOS memory in which there are no junctions. These junction-less (JL) devices are realized on vertical Si nanowire gate all-around structure with channel dimension down to 20nm and have comparable electrical characteristics (SS &#x003C; 70mV/dec, leakage current &#x003C;1&#x00D7;10<sup>&#x2212;12</sup> A and a memory(More)
A model is presented for the linear Rayleigh-Taylor instability taking place at the early stage of acceleration of an elastic-plastic solid, when the shock wave is still running into the solid and is driven by a time varying pressure on the interface. When the the shock is formed sufficiently close to the interface, this stage is considered to follow a(More)
The contribution of polluted dust transported from local and distal sources remains poorly constrained due to their similar geophysical and geochemical properties. We sampled aerosols in three cities in northern China (Xi'an, Beijing, Xifeng) during the spring of 2009 to determine dust flux, magnetic susceptibility and elemental concentrations. Combining(More)
A previously developed model for the Rayleigh-Taylor instability at an interface between an elastoplastic solid and a viscous fluid [Piriz, Sun, and Tahir, Phys. Rev. E 88, 023026 (2013)] has been used for calculating the time evolution of the perturbations in terms of the mechanical properties of the solid and the liquid, as well as of the initial(More)
Brain-derived neurotrophic factor (BDNF) plays important roles in neuronal development and reproductive action. Abnormal expression of BDNF gene has been detected in human sperm and seminal serum. In the present study, we investigated the possible association of G196A and C270T polymorphism of BDNF gene with male infertility. The genotypes of the G196A and(More)
