Continual scaling of the CMOS technology requires thinner gate dielectric to maintain high performance. However, when moving into the sub-45 nm CMOS generation, the traditional poly-Si gate approach cannot effectively reduce the gate thickness further due to the poly-depletion effect. Fully silicided Ni metal gate (FUSI) has been proven to be a promising solution. Ni FUSI metal gate can signifi...
This is our initial response towards fabricating a magnetic filled polymer composite samples potentially used as electromagnetic waves detector. Samples of lanthanum yttrium iron garnet Y3.0-XLaXFe5O12 (where x = 0, 0.5 ,1.0, 1.5 , 2.0, 2.5, 3.0 ) were synthesized by conventional solid state technique. We used simple casting technique to fabricate the Y3.0XLaXFe5O12-PVA composite. The samples w...
Laser therapy has the potential to be an effective, minimally invasive procedure in periodontal therapy. The aim of the present review was to survey the relevant literature on the clinical application of lasers as a minimally invasive treatment for periodontitis and peri-implant disease. Currently, there are a large number of published clinical studies and case reports that evaluate the adjunct...
A multi–layer gadolinium–doped yttrium oxide thin film was deposited in a combinatorial fashion on a Si (001) substrate using radio–frequency magnetron sputtering. Alternating layers of Y2O3 and Gd were deposited for a total of 9 layers. The film was homogenized in composition by an 850 C 12 hour thermal treatment producing a range of composition from Y1.96Gd0.04O3 – Y1.54Gd0.46O3 in a single f...
A new metallofullerene Y(3)N@C(78)-C(2) was synthesized and characterized. It was shown that Y(3)N@C(78) has an unconventional C(78)-C(2) cage with two pairs of fused pentagons closely bonded with two yttrium atoms. DFT calculations showed that the size of the ionic radii of the metals forming the caged cluster plays an important role in the non-isolated-pentagon-rule-feature of the C(78) cage.
A facile method for the preparation of highly active and enantioselective yttrium precatalysts for asymmetric hydroamination of gem-disubstituted aminoalkenes, from the combination of YCl(3) or YCl(3)(THF)(3.5) with ligand (R)- and n-BuLi is described.
