Current induced spin wave excitations in spin transfer torque nano-contacts are known as a promising way to generate exchange-dominated spin waves at the nano-scale. It has been shown that when these systems are magnetized in the film plane, broken spatial symmetry of the field around the nano-contact induced by the Oersted field opens the possibility for spin wave mode co-existence including a...

By utilizing the strongly induced plasmon coupling between discrete nano-antennas and quantitatively controlling the crystalline proportions of an underlying Ge2Sb2Te5 (GST) phase-change thin layer, we show that nanoscale light localizations in the immediate proximity of plasmonic nano-antennas can be spatially positioned. Isolated energy hot-spots at a subwavelength scale can be created and ad...

have been used as the active channel in nano-BioFETs through bottom-up approaches. [ 8 ] Wafer scale nano-BioFETs have been successfully fabricated through complementary metal oxide semiconductor (CMOS) compatible top-down microfabrication process which facilitates the mass production of such devices. [ 9 ] In any case, nano-BioFETs share the same sensing principle by affi nity-based detection,...

This paper presents a detailed study of the present VLSI technological aspects, importance and their replacement or combination with the Nanotechnology in the VLSI world of silicon semiconductors. Here authors bring out the nanotechnology in Silicon world which invariably means shrinking geometry of CMOS devices to nano scale. This also refers to a new world of nanotechnology where chemists are...

In electrochemical loading of Pd with deuterium, it has been known that attaining a D/Pd value larger than 0.88 is necessary for triggering excess heat effects [1]. It has been reported by Arata and Zhang that the heat arising from D-D nuclear fusion reaction in solid is observed simply by pressurizing nano-Pd/ZrO2 system with deuterium gas [2]. It seems that nano-scale Pd particles absorb more...

Nanosphere lithography (NSL) has been studied as the effective method of fabricating nano-scale array. This paper presents template-assisted NSL to obtain high-quality crystal in regularity and coverage. A periodic array of 100 nm deep nano trenches with two different widths, 400 and 450 nm was fabricated by nano imprint lithography (NIL), and used as the template. When polystyrene nanospheres ...

Quantum-mechanical molecular-dynamics simulations are carried out to explore possible precursor states of nano-polycrystalline diamond, a novel ultra-hard material produced directly from graphite. Large-scale simulation with 10 atoms is realized by using the ‘orderN ’ simulation code ‘ELSES’ (http://www.elses.jp). The simulation starts with a diamond structure that contains initial structural d...

In this study, nano-scale honeycomb-shaped structures with anti-reflection properties were successfully formed on SiC. The surface of 4H-SiC wafer after a conventional photolithography process was etched by inductively coupled plasma. We demonstrate that the reflection characteristic of the fabricated photodiodes has significantly reduced by 55% compared with the reference devices. As a result,...

Demonstrated that analog of diffractive and refractive 3D optics in free space can be developed to manipulate surface waves such as surface plasmon polaritons (SPPs). It has been shown that an air-gap control of a floating dielectric block can generate the dynamic phase and amplitude modulation of the SPP transmission coefficient. Unlike conventional bulk optics, the nano-scale surface optics f...

Discovering the mechanical properties of biological composite structures at the Nano-scale is much interesting today. Top Neck mollusk shells are amongst biomaterials Nano-Composite that their layered structures are composed of organic and inorganic materials. Since the Nano indentation process is known as an efficient method to determine mechanical properties like elastic modulus and hardness ...
