A method of selective growth of carbon nano-structures on silicon substrates, comprising definition of the predetermined area on Si substrates to be grown carbon nano-structures, formation of metal-silicides on the predetermined area on the said Si substrates to be grown carbon nano-structures, and growth of carbon nano-structures on the said metal-silicides by chemical vapor deposition method. Locations of the said metal-silicides on the said Si substrates are growth area of the nano-structures, whereby function of selective growth of carbon nano-structures on Si substrates can be achieved. Besides, the said metal-silicides area is manufactured by semiconductor processes, and is directly compatible with IC processes.

Elastomer nanocomposites consisting of nitrile butadiene rubber (NBR) latex and layered silicates are prepared by a modified latex shear blending process aided with ball milling. The mode of dispersion of layered silicates in NBR is partially exfoliated and intercalated when the concentration of layered silicates is below 7.5 wt%, as evidenced by transmission electron microscopy and X-ray diffraction results. The tensile and tear mechanical properties are much higher than that of neat NBR. Specifically, the tensile and tear mechanical properties of the NBR/layered silicates increase by 200 and 60%, respectively. The decomposition temperature of the nanocomposites increases slightly.

This study proposes a modification of existing entanglement purification protocols for pairs of qubits. The proposed protocol restores a desired pure state by standard purification local operations and classical communications, without preliminarily estimating the entangled state to be purified. The proposed protocol is demonstrated to outperform the previously proposed IBM and Oxford protocols. (C) 2004 Elsevier B.V. All rights reserved.

We have discovered a new type of small molecular host material based on aluminum(III) 8-hydroxyquinolates, Al(Saq)(3), which was synthesized with three 5-(N-ethylanilinesulfonamide)-8-quinolinoline as bidentate ligands. By X-ray diffraction crystallographic analysis, the crystals of meridional Al(Saq)(3) are monoclinic, space group P2(1)/c, a = 17.952(3) Angstrom, b = 17.7160 Angstrom, c = 17.080(3) Angstrom, beta = 99.895(4)degrees. Its peak photoluminescence in solid phase appears at 488 nm. Its LUMO/HOMO (-3.13/-6.04 eV) and optical band gap (E-g 2.91 eV) were determined by cyclic voltammetry. In solid thin film morphological investigation, it shows good thermal properties and high quantum efficiency. When doped with 0.7 wt % of the high fluorescent green dopant 10-(2-benzothiazolyl)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro-1H,5H,11H-benzo-[l]pyrano[6,7,8-ij]quinolizin-11-one (C-545T), energy transfer from Al-(Saq)(3) to dopant will occur and high green light emission can be achieved. For fabrication of OLEDs using spin-coating techniques, its electroluminescence is at 1931 CIEx,y (0.21, 0.41).
Phase frequency detector with a narrow control pulse
(2004-07-29)

A phase frequency detector with a narrow control pulse comprises mainly two substantially equivalent phase latches with a narrow control pulse, and a reset signal generating unit. Each phase latch of a narrow control pulse has a clock pulse input end and a signal output end. Both latches also be connected to the reset signal generating unit. The logic value of each signal output end is decided by which clock pulse input appears first. The reset signal generating unit decides whether or not to generate a reset signal according to the logic values of both signal output ends. The reset signal is then sent to both phase latches of a narrow control pulse, if generated. The present invention can be implemented by a simple circuit. Comparing with the RS NAND PFD or master-slave D PFD, the PFD of the invention has the advantages of faster speed, saving more power and smaller IC chip area. Comparing with dynamic PFD, because the PFD of the invention has a feedback circuit, the storage charges of internal nodes will not be lost due to the leakage current and therefore the working frequency range is wider.
Ultra-shallow junction formation for nano MOS devices using amorphous-si capping layer

The present invention provides a new ultra-shallow junction formation method for nano-MOS technology applications by using conventional ion implantation and rapid thermal annealing techniques without requirement of low energy implant equipments to fabricate ultra-shallow junctions. Diffusion from implanted amorphous silicon (DIA) is performed by junction implant through an amorphous capping layer; the amorphous layer thus acts as a surface solid diffusion source during annealing. A thin oxide is deposited to serve as etching stop layer beneath the amorphous layer. This bilayer amorphous-oxide structure enables easy removal of the amorphous layer and provides good process control and device reliability. By using amorphous silicon layer as the diffusion source for junction formation, implant defects are reduced. Defect-free ultra-shallow junctions can be formed.
Spectroscopy and femtosecond dynamics of type-II CdSe/ZnTe core-shell semiconductor synthesized via the CdO precursor

CdSe/ZnTe type-II quantum dots (QDs) synthesized via the CdO precursor are reported. Spectroscopic and femtosecond dynamic measurements reveal that the rate of photoinduced electron/hole spatial separation decreases with increases in the size of the core, and it is independent of the thickness of the shell in the CdSe/ZnTe QDs. The results are consistent with the binding strength of the electron and hole confined at the center of CdSe. The correlation between the core/shell size and the electron/hole spatial separation rate resolved in this study may provide valuable information for applications where rapid photoinduced carrier separation followed by charge transfer into a matrix or electrode is crucial, such as in photovoltaic devices.
